Addressed an issue where the Spinjitzu Initiate achievement would not progress. This also allows mission tasks that specify that the player must get a kill on an enemy with a skill to progress. Tested mission 1935 and 1139 and both missions progressed and completed as intended.
Remove the CDClientDatabase::ExecuteQueryWithArgs() function and replace
it with CDClientDatabase::CreatePreppedStmt().
This prevents a developer from accidently using %s, or incorrectly
passing std::string, and causing a silent error.
* add HandleUnmanaged overload to account for skill source
* add source to buff damage skill call to credit players for kills
* use LWOOBJID_EMPTY default arg & behaviorcontext constructor
