Message:

• Radar now working like before
• but more of a svn save..

There is class called Radar which takes care of the focus and all objects that can be displayed on a Radar.
The actual visual implementation is in HUDRadar.
To make a object radar viewable, simply implement RadarViewable and set the WorldEntitiy pointer in the constructor (assertation will fail otherwise!).
You can also set a camouflage value between 0 and 1 that tells how good a radar can see an object.
The HUDRadar (or another one) on the other side has a sensitivity between 0 and 1. So only if the sensitivity is higher than the camouflage value, the object gets displayed.
