Add more optional stuff

[nonder]

Hello. I got one idea today.

Put somewhere in map shop (with driver as layout object - and some barriers+parking near it) where other drivers can buy some additional stuff (via insim buttons). It will make gameplay longer and nicer. We just need some things to buy.

We have only locator now. There can be radar(which will cost about 20 000 so not everybody can have it - this can partially solve the problem when speedtrap fines chased car), compass (http://forum.city-driving.co.uk/showthread.php?tid=5114 10 000€), GPS - this can be one arrow on screen which show shortest path to target (!gps <username>) - very usefull for tows, cops and normal drivers too - (70 000€ - it is little expensive because it gives cop advantage - or other way is to disable it when cop is in chase), and many other things...
