add a readme, note the other native dependencies needed for native linux builds
sync up to latest exus-build shared bits
adding dependency on robovm-dist at 0.0.9.mvn.
whoops, these need to remain following the import of the common build configs
unpack the robovm dist tar and use those libraries and executables; you're now free from needed robovm installed on your system and we've got everything strongly linked.

well, aside from platform specific needs as noted in the readme.  which are considerably harder to address, so if anyone out there can make a cross-platform c build toolchain and headers set and get that to me in a tarball, that'd be great.
unpack-robovm is actually a need for compiling because the apple code links against some apis in robovm jars.
admit to eclipse project config files.
