Minor Updates
Merge pull request #131 from hazendaz/master

Minor Cleanup & Travis-ci
Added Travis-CI badge.
Added coverity

added coverity for more indepth scanning as part of travis ci.  To use
this, it requires setup over on coverity.  Currently it is coded to my
location which should be fine for the time being as it also requires to
be run on special branch that needs setup for it to actually do
anything.
Code Cleanup

Clearing more warnings / cleaning library.
Adding Coveralls plus badges

Adding coveralls (initial testing)
Adding badge for maven central to waffle-jna
Adding badge for coverity
