Refined ban command

Added error message and changed "Banned" to "Preparing ban" on the
"/ban" command.
Minor update and hotfix for last large update

Added a directory check/auto-creation for DIRECTORY_VEHICLESPAWNS
(./scriptfiles/Vehicles/)

Refined the ban statements to use COLLATE NOCASE instead of LOWER().

Fixed the "Wood Ramp" item to actually be a ramp.

Added Motor item to loot spawns, this item is for making Locksmith Kits.

Fixed some bugs with the last change to vehicle enter/exit code. UI now
properly shows/hides for entering/exiting vehicles as driver or
passenger.
