Feature/satellites (#325)

Browse Source 
* Initial commit of satellites test branch

* Modified code to work with batch TLE files from online links specified in .mod file. Does not yet auto-download the files.

* Added debug function to mod file for testing static points in orbit

* Fixed time offset bug that was corrupting satellite positions

* Minor changes for debug output and camera position.

* Changed to circle billboard for rendering satellite position

* Added satellite group name to each renderable title, and keyboard shortcuts for toggling visibility

* Added support for using ghoul luasocket lib to download latest satellite TLE files from celestrak.com

* Adding reference to updated Ghoul submodule containing luasocket changes

* Updating reference to latest Ghoul submodule in feature/satellites

* Updated reference to new ghoul version

* Updated reference to new ghoul submodule version for satellites

* Updated reference to new ghoul submodule version for satellits

* Updated versions of TLE files

* Added new Lua-accessible downloader available for scene loading

* Improved error handling for TLE files

* Updated submodule reference for ext/ghoul prior to luasocket addition

* Update SGCT reference
