Fix raid groups load from DB and save to DB.

Fixes issue #299.

- In table GROUPS, since rev 7841, isRaid is used to store the groupType. The DB was not updated. this is now fixed.
- Fix isRaid set to 1 when group converted to raid (shall be the groupType).
- Fix isRaidGroup check as groupType is now a set of flags.
- Fix dungeon/raid check when difficulty change.
