Bumped version number following the release of 2.0.1.
Switched NetBeans to use Gradle project files.
GPG signing of JARs is now only required for releases.
FileGDB native code is now loaded from java.library.path if possible.
Improved native code loading error messages.
Gradle tests now depend upon packaging the native libraries.
Fixes #2 on GitHub.  slf4j-simple is now a test dependency.
Merge pull request #3 from jgibson/master

Optional signing and some other tweaks. I'm going to assume that the random main is not going to cause problems with slf4j-simple.
