Core/Spells: Fixed charge effects with non-explicit targets
Core/Loot: Only 3 items of the same entry can drop on 25 man raid difficulties and 1 everywhere else (non-raid or 10 man)
Core/Loot: Minor change to previous commit, thanks Vincent_Michael for reminding me about this method in Map class
Core/RA: Fix a possible crash

Caused when RASocket::handle_close (event-driven) would delete the underlying object before RASocket::commandFinished callback was executed for that object. Dereferencing freed pointers is bad.
Core/RA: Addition to previous crashfix

To make sure it also works for sessions that use more than 1 command
before closing.
Core/LFG: Fix a crash

Fix a crash in case a player is recognized as in a LFG dungeon, but without a valid group
Core/Handlers: Fix a crash in HandleCharFactionOrRaceChange

Ensure there's always valid character name data present, even for
characters that were manually inserted into the database, by adding
character name data on char enum if needed.
Core/Handlers: Prevent some cheating in CharacterHandler

Prevents factionchanging and char customising of characters that do not
belong to the current account.
Core/Handlers: Missing returns after KickPlayer() call
Core/Maps: Prevent creating maps without a valid Map.dbc entry

Closes #9181
