This fixes a bewildering but fairly minor bug in the pack task with the default GUI assets, affecting at least the scene2d.ui template. If you depended on gdx-liftoff to generate GUI assets before, which is unlikely because they didn't work at all, they have been moved around and are now correctly in assets/ui/. It updates the dependency version for RoboVM/MobiVM, and also updates the version for the crowd-pleasing library typing-label along with its new GWT dependency info. The .png assets inside the jar have been optimized as best as I can losslessly, so the jar is a little smaller and project file sizes may be too. A few leftover assets from SquidSetup, which uses a squid tentacle as an icon, have been swapped out for the consistent space shuttle liftoff icon used here.
