- Fixed main.sql adding a key on char_id rather than account_id for the char table.

- Cleaned up character saving in char-sql, it no longer needs to query the database to see if the player exists on each char-save, instead it checks the received data against the online-players db. 
- Added an error message on the char-server when the received player data size does not matches with the expected size (should avoid the crash that happens on such a memcpy).
