2.1b2:
	Was truely ported to ROM for the first time - thanks go to Anthony
	Tregre.

2.1b4:
	Did lots of changes, I don't remember all of them...

	morannon:~>
	... as you can see, enough was changed :)

2.2:
	Found  bad crash bug - since the vehicle is an object, it can be
	flagged "take", and taken. enter vehicle,take vehicle, drive
	<direction> --- *boom*. Fixed.
