[TASK] Find functional tests automatically, optimize travis-ci

Simalar to UnitTests.xml, FunctionalTests.xml no longer register
single test suites but find all functional tests cases using a
wildcard.

For travis-ci, single tests cases are now given to parallel using
gnu find. This leads to a nice performance improvement on travis
since more but shorter processes are executed, sharing the available
hardware more effectively.
