Maven packaging (#18)

* Change maven id and project name to just "jssc" at "io.github.java-native" namespace
* Adds two releasable jars (platform-specific jar and uber jar).  TODO: add non-shaded fat jar #21
* Allow cmake to parse version info from pom.xml
* Adds ability to skip native compilation steps including cmake and tests
* Leverages maven-assembly-plugin for better classifier to the default artifact
* Alphabetize, organize and remove hard-coding of dependencies/variables
* Adds Travis-CI for many platforms.  Note, some binaries are not yet usable, sorry!
* Adds Ubuntu 14.04 cross-compiled binaries to the source tree. TODO: Move to git-lfs
* Add LICENSE to pom.xml (#22)
