[Demo] Include satellite tracker in demo build

This integrates Satellite Tracker into demo build in support of nasa/mct#117, and does other preparation for forthcoming MCT demo.

Addressed:
* Put together working Maven build for satellite plugin (see nasa/mct#117, nasa/MCT-Plugins#76)
* Updated references to recently-deprecated icon API (see nasa/mct#184 and nasa/mct#145)
* Removed code related to IzPack installer, and other clutter from quickstart assembly (installer no longer necessary since "unzip and run" is supported, nasa/mct#109)
* Updated quickstart assembly to remove custom persistence plugin (no longer needed due to update to Derby, nasa/mct#118)
* Resolved various warnings which were causing build issues under Maven 3 (see nasa/mct#107)

Modifications to continuous build will be required to reflect appropriate artifacts after this change.
