* Fix some codestyle, fix some typos
* Change CMakeLists for: Custom (can be uncommented), Events, World
** Custom is theoretically unchanged. You can, however, uncomment the glob_recurse that initializes every file within. This might be easier for beginners.
* Introducing the IP Based Action Log System:
** On several different actions, e.g. Login, Character Login, etc., a new entry is added
** Can be logged on and off in worldserver config
*** Disabled by default to prevent increased log db size for unknowing users.
* Add a new row to account table called 'last_attempt_ip'
** Lists the last ip trying to connect to the account
* Add a new type of HookScripts: AccountScript
** Includes: OnAccountLogin, OnFailedAccountLogin, OnEmailChange, OnFailedChange, OnPasswordChange, OnFailedPasswordChange
* Added new Hook to PlayerScripts: OnFailedPlayerDelete
* Added new variables to PlayerScripts: OnPlayerDelete
Fix a database race condition in authserver that would delay the account ban expiry by 1 login because the query that would have removed the ban was executed asynchronously.
Fix a database race condition between authserver saving session key to database asynchronously and worldserver reading it; session key is now saved synchronously.
Mitigate DoS attacks to authserver like "Wow Auth Flooder.exe" by allowing a finite number of AUTH_LOGON_CHALLEGE packets in a row from same socket, 3 sounds like a reasonable limit.
New column in account table is a base32 of token key bytes,
coincidentally it is the same format Google's Authenticator Android app uses.
If you want that to work, set system time on server correctly and use ntpd.

Remove mutex from BigNumber class - it didn't do what it was advertised to do - consider using the "locked" array outside of the function in which it was "locked".
Fixes RASocket::authenticate crash
"MSG_NOSIGNAL:
If you send() to a remote host which is no longer recv()ing, you'll typically get the signal SIGPIPE. Adding this flag prevents that signal from being raised."
Closes#5040
Thanks to @derex for the hint
- Logging System is asyncronous to improve performance.
- Each msg and Logger has a Log Type and Log Level assigned. Each msg is assigned the Logger of same Log Type or "root" Logger is selected if there is no Logger configured for the given Log Type
- Loggers have a list of Appenders to send the msg to. The Msg in the Logger is not sent to Appenders if the msg LogLevel is lower than Logger LogLevel.
- There are three (at the moment) types of Appenders: Console, File or DB (this is WIP, not working ATM). Msg is not written to the resource if msg LogLevel is lower than Appender LogLevel.
- Appender and Console Log levels can be changed while server is active with command '.set loglevel (a/l) name level'
Explanation of use with Sample config:
Appender.Console.Type=1 (1 = Console)
Appender.Console.Level=2 (2 = Debug)
Appender.Server.Type=2 (2 = File)
Appender.Server.Level=3 (3 = Info)
Appender.Server.File=Server.log
Appender.SQL.Type=2 (2 = File)
Appender.SQL.Level=1 (1 = Trace)
Appender.SQL.File=sql.log
Appenders=Console Server (NOTE: SQL has not been included here... that will make core ignore the config for "SQL" as it's not in this list)
Logger.root.Type=0 (0 = Default - if it's not created by config, server will create it with LogLevel = DISABLED)
Logger.root.Level=5 (5 = Error)
Logger.root.Appenders=Console
Logger.SQL.Type=26 (26 = SQL)
Logger.SQL.Level=3 (2 = Debug)
Logger.SQL.Appenders=Console Server SQL
Logger.SomeRandomName.Type=24 (24 = Guild)
Logger.SomeRandomName.Level=5 (5 = Error)
Loggers=root SQL SomeRandomName
* At loading Appender SQL will be ignored, as it's not present on "Appenders"
* sLog->outDebug(LOG_FILTER_GUILD, "Some log msg related to Guilds")
- Msg is sent to Logger of Type LOG_FILTER_GUILD (24). Logger with name SomeRandomName is found but it's LogLevel = 5 and Msg LogLevel=2... Msg is not logged
* sLog->outError(LOG_FILTER_GUILD, "Some error log msg related to Guilds")
- Msg is sent to Logger of Type LOG_FILTER_GUILD (24). Logger with name SomeRandomeName is found with proper LogLevel but Logger does not have any Appenders assigned to that logger... Msg is not logged
* sLog->outDebug(LOG_FILTER_SQL, "Some msg related to SQLs")
- Msg is sent to Logger SQL (matches type), as it matches LogLevel the msg is sent to Appenders Console, Server and SQL
- Appender Console has lower Log Level: Msg is logged to Console
- Appender Server has higher Log Level: Msg is not logged to file
- Appender SQL has lower Log Level: Msg is logged to file sql.log
* sLog->outDebug(LOG_FILTER_BATTLEGROUND, "Some msg related to Battelgrounds")
- Msg is sent to Logger root (Type 0) as no Logger was found with Type LOG_FILTER_BATTLEGROUND (13). As Logger has higher LogLevel msg is not sent to any appender
* sLog->outError(LOG_FILTER_BATTLEGROUND, "Some error msg related to Battelgrounds")
- Msg is sent to Logger root (Type 0) as no Logger was found with Type LOG_FILTER_BATTLEGROUND (13). Msg has lower LogLevel and is sent to Appender Console
- Appender Console has lower LogLevel: Msg is logged to Console
Note: The default config file action for clients failing the checks can be changed for each check via the characters.warden_action table
