Dependencies

Bumping to new default kafka version

Make new profile if it doesn't exist, matching kafka version as id tag.
Ensure the new profile is the only one active pr default with activation->activeByDefault
Change release profile to have the same stuff in it's profile. (used for buildservers who signs artifacts with GPG and attach javadocs and pushes to public M2 repository..)
Update MVN_PROFILE in Makefile
Update .travis and add it into the matrix, so CI runs tests for your kafka version profile.

Profit.

scala versions

Ensure you check mvn dependency:tree and ensure you don't pull in libraries compiled with different scala versions. This is bad.
