SSTU - Shadow Space Technologies Unlimited

* Add CTT patch.  It rearranges things for a significantly increased overall difficulty.  Some parts unlock 2, 3, or even 4 nodes later than they do under stock balancing.
* Add a separate SSTU-OptionalPatches folder to distribution.  These are a set of potentially destructive patches, but also contain some cool stuff (better USI and NF integration, editor parts list bloat cleanup)
* CHANGE - SUBMODELS will now automatically include any parent transforms; only the bottom-most children for any branch need to be specified.
* FIX - SSTUModularHeatShield - now properly calculates adjusted cost for current size and setup.
* FIX - SSTUInflatable module -- only compress resources if the VC that was changed is on the same part as the inflatable module.
* CHANGE - ST-GEN-DSP-DOS-XXX panels now use colored specular shader, update textures for separate spec texture, add shader-assignment patches.
* CHANGE - clean up some misc inefficiencies in SSTUSolarPanelDeployable
* CHANGE - Update VolumeContainer GUI any time volume is updated.  Disable GUI fields if volume==0.
* CHANGE - Add basic support for 'upgradeUnlockName' to SSTU-ModelData model definitions.  Currently only supported at the module level for solar panels and docking ports on StationCore parts, but will be expanded upon in the future to include various adapters and tank variants.
* CHANGE - SSTUModularStationCore - add support for allowing solar panels and docking ports to be unlocked
* CHANGE - Add gray and green textures for ST-DOS parts.

#### Balance Changes
* ST-DOS / ST-HAB - Add solar panel and docking port upgrade unlock parts (career mode).  These need to be acquired and purchased prior to being able to use solar panels or docking port options.
* ST-MST cost updated to 80k
* ST-DSP Solar panels distributed through the electrics tech nodes
* ST-DOS - update antenna config to have proper range for that antenna type (2g)
* ST-DOS - Add mecheb module though MJ patch.
* SC-MFT-D/R/S - moved to fuelSystems
* SC-ENG-RD-107/108/0110 - moved to heavyRocketry
* SC-MCB-A moved to advMetalworks, changed to Structural category, cost and mass now specified
* SC-GEN-FR-N/W - added cost and mass specifications
* SC-GEN-MHS - added cost specification
* SC-GEN-PPC moved to basicScience tech node
* SC-GEN-RBDC - cost and price updated
* SC-GEN-RMB - moved to miniaturization tech node
* SC-A-SM/OM/DM - moved to heavyRocketry
* SC-A-SMX - moved to unmannedTech
* ST-DOS/COS/HAB/CFG - add USI-LS support and initial configs
* SC-A/B/C/E - update USI-LS configs for new supplies usage.  Also offset pod mass by the supplies mass to restore intended balance for those parts.
