Updated player deletion code to accommodate tables that do not use the column name citizenid

[tlsharkie]

Updated player deletion code in server/player.lua to accommodate tables that do not use the column name citizenid.
Many scripts use other column names to store the citizenid but contain data that should be deleted upon character deletion. This leads to excess data build up in the database that is no longer needed and currently requires manual effort to clean out the database.

New format for playertables now contains table and key variables (primary key column name)
and updated SQL commands in DeleteCharacter and ForceDeleteCharacter to handle variable column names

--- 'table' is the new SQL table name
--- 'key' is the column name which contains the 'citizenid'
{ table = 'players', key = 'citizenid' }
