Added /doorlock and /doorunlock

I felt these features were missing - especially if we want to lock
people out of unownable doors.
Forgot to set the messages to client only.
Added ignoring file for config and translations.
Made sure players were valid when sending their char.
Fixed amount wording and logic.
Changed it so data saving for vendors is instant.
Fixed missing column in .sql file.
Fixed vendor prices not using item's price if one isn't defined.
Changed variable names which fixes #41.
Merge pull request #36 from NightmareX91/master
