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.
