Minimap in Vechile HUD - Update vehicle_hud.lua

[Xuptio]

This feature has the 'new car smell' feeling to it, Carrier Command 2.5 sort of feel...
A novel but visually appealing feature of a minimap when using the camera of any vehicle.
Distinct from the main large map enabled by the tab button, this minimap looks more fitting to the rest of the vehicle HUD. Could maybe add labels to the big map in another feature add...
Features:
A white triangle faces and points in the direction of the players vehicle.
Enemy and allied vehicles have string tags in the colour of their team.
Ocean is green and transparent so as not to be too distracting
Land is purple

Added code for rendering minimap while in vehicle control.
code block at 327 for calculating offsets and render minimap
added function 987
update to fuel %, estimated mins, efficiency HUD offsets ~4914

TODO
Turrets not with names
Some vehicle labels might not be correct eg - Bear 'BER', wasn't sure what was the acronym they use in game.

Hi Xuptio, I think this is very cool, but i find it too distracting. It would be nice if it were possible to set (rather than toggle) the mini map on/off as a game setting rather than have it always on.

Oh, if you want the vehicle acronyms they are available via the e_loc values. But, I don't think its worth displaying the vehicle types, in most cases things will be too cluttered to read.

This might be nice as a stand-alone feature, or as one that can be toggled on via a setting
