Preeliminary DB Support

Current State:
- Everything should be working, with periodic 1 minute saves & OnLeave
save;
- Haven't tested mysql;
- If you get errors to report, please do so. I was getting unhandled
exceptions  which I did not manage to reproduce.
Fixed DB - MySql should now work
Fixed DB attributing stats to wrong accs

The above, and:
- Added Playing time table (shown with /stat)
Quickfix on OnPlayerLogin

Players should now be hooked correctly to their Player object upon
rejoin.
Quickfix #2

Data was actually not being loaded from the db...

Statistics non-working version of List<Player>.

Should fix everything DB-related. Can now proceed into adding new content and fixing non-related bugs.
