Updated Remove Class Items

Now includes all class assigned items (not just the default dark rp entities) for class based removal.
Included additional config "ignoreClassItem" table to exclude the termination of specific class based entities. Format: GAMEMODE.Config.ignoreClassItem = { ["entityclass"] = true }
Merge branch 'patch-3' of github.com:johndoeno001/DarkRP
Amended #1364

The variable name didn't properly indicate the function.
Added config variable to default config
