Added loot table for deathmatching

Removed the old "weapons everywhere" loot table file and added an
improved one that contains weapons, meds, food and vehicle supplies (all
the essentials) instantly turns SS into a simple freeroam deathmatching
server!
Split up vehicle data into two files

Split saved vehicle data similar to player data, one file for properties
such as health and model, another file purely for inventory contents.
It's slower, but easier to manage and add more saved properties.

Added a super secret future feature item...

Also fixed a bug with auto-create settings file, "&" character doesn't
display in gamemode name properly.
