Initial mavenization, including example keystore for signing jars

All tests are passing in maven.  The jar file manifest looks good from what I can tell.  I was able to create an intellij project using the "import maven project" feature, and running tests from within intellij works just fine.

I set the version as "1.0-SNAPSHOT".  I figure when there are official releases, folks will want to branch/tag the source and edit the version accordingly.
Is it necessary to include this library? Based on http://sourceforge.net/p/picard/wiki/IntelDeflater/ it seems it's optional. I would probably make it much easier not to include it due to licensing issues and such. Or is the idea not to package it with the jar?
