SQLDatabaseManager optimizations, async profile loading -t00thpick1, zreed

Browse Source 
This commit changes our shared connection into a connection pool utility to prevent
thread locks from multiple actions attempting to access the database at the same time.
In additon,  profile loading has been moved off the main thread at login time, to
allieviate the performance issues caused by it.

Fixes #2138, Fixes #2119, Fixes #1982, Fixes #1953
