More incarnator work.

Hectors now spawn at the correct heading. I also changed the name of the XML attribute from `angle` to `heading` to be more descriptive.
Finished up Phosphorus, fixed incarns in Bwadi.
Minor updates to geom.py

working on using far less geoms. ramps don't work, neither do ypr on anything.
Flattened geoms and flattened physics.
Merged from jonathanvoss, fixed FreeSolid spawning

That is, I fixed the FreeSolids that fall from the sky whenever P is pressed. They were crashing the app after jonathanvoss's awesome static geometry updates. I also tweaked the Hector colors a bit so that it is more visible in all of these green maps we have.
Added <static> tags to finished maps.
Fixed a bug with starfields that broke lighting.

We should look into whether or not it is possible to make starfields more efficient, using our new node/geometry flattening knowledge.
Fixed bug that occurred when a map had two static tags

Forgot to wrap composite objects in effects. Now you can have groups of static holograms and static semitransparent objects, however semitransparent objects are opaque to other objects within the static tag.
