Added new type-safe cast functions.

This, when properly used, should get rid of most memory corruption issues,
currently, casting types C-style with no checks leads to some abstract crashing.
Functionality is same as with dynamic_cast<>, but with no RTTI check - so when
casting into invalid type you will receive NULL, and most probably crash.
At the same time, i took the liberty to convert most Player* casts to ToPlayer().
Still needs crapload of casts being moved to new facility.
