Update Xcode project
Merge remote-tracking branch 'upstream/master' into Xcode
#2128 -  Sort missions list
New table widget with column sort support
SmartTable: added ui:Label as a default widget for cells. Now user has no need to specify widgets if he's okay with Labels in table.
Stable sort.
Added a new ground station called "new_ground"!
It's a six bay station made from open source models and textures, plus some that I've made myself.
Also disabled the placeholder 4 bay station.
Oops, deleted one of my source textures, not used in final.
Create one StaticGeometry node per aiMesh, and reuse them when possible
Updated to reduce number of meshes, unified some textures.
The illumination for the lights is now part of the liftcolumn_illum texture, so that I can add more colour and glowy bits in future.
Removed one of the meshes.
After struggling with this I give up for now on getting the low-res LOD to work.
It totally fucks the tags it seems, that means I can't retrieve the docking bays or stages and then the wheels fall off.
Included is the low-LOD and the docking stages have been split out again.

Add new ellipsoid terrain height class.

This class creates an ellipsoid surface representing equatorial bulges
for rotating bodies by returning the height value between a point on a
sphere of Polar radius and a point on the ellipsoid surface in the
center to Polar radius line (using the aspect ratio which gives
Equatorial to Polar radius).
allow CustomBody to control SystemBody aspect ratio
