Currently the target/ folder is not in .gitignore this gives me changes
when I compile the source.

 - Added toolchain plugin so we can build against JDK1.6 while still using maven (needs 1.7+)
 - Added animal-sniffer to verify we aren't using any JDK API out of 1.6
 - Added test plugin (maven-exec) and disabled surefire since we dont use JUnit
 - Correctly modeled the dependencies with appropriate scope
 - Added some missing files to gitignore
 - Added Maven wrapper so setup is painless for new developers
 - Added README.md that explains use of toolchains.xml and maven wrapper
