XLRstats: many changes :
- more changes towards sqlite compatibility (see `cursor.rowcount` and `NOW()`)
- improved config file reading (bug fix + handling of junk values + refactoring)
- add tests for xlrstats storage functions (test only with sqlite as the FakeConsole uses sqlite only)
XLRstats: fix bug in get_PlayerStats which would not set the kfactor property when no stat exists for a player
XLRstats: minor fix in the xlrtopstats SQL query that only affects automated tests
commenting debug. no longer needed
