somewhat working arc camera

camera doesn't follow correctly if you're viewing the ship from the side
unforunately.  Have to work on it some more.
minor tweak, camera still wobbles
Fixed camera rotations

Camera now rotates correctly and will stick in place around the ship.

there is still a bit of a wobble when steering the ship around.  I don't
know if it will be noticeable when we have a skybox though.
Created new class to hold static models.

Static Models should be good for populating the world with debris to
show movement, if we chose to go that route, and should serve as an
initial way to stick objects into the world with which we can interact
(such as our goals).
Initial Collision Logic, HUD Overlay

Both of these things need more work before they work the way we'd like
them to.
Added asteroids, fixed constructor

Whole bunch of spacerocks in there now. Next step is to set it up such
that they get randomized when the "map" is created so that each time you
play the course is different, and add/fix collision.
Merge remote-tracking branch 'origin/master' into unstable

Conflicts:
	SolarSailor/SolarSailor/Game1.cs
	SolarSailor/SolarSailor/SolarSailor.csproj.Debug.cachefile
	SolarSailor/SolarSailorContent/SolarSailorContent.contentproj
fixing up merge of master and unstable branches

marc commited to master so I had to merge master and the unstable
branches that joe had done.   Should be working pretty well now.
