TychoBuild

Created originally on Bitbucket by makkimesser (Makki Messer)

Was already merged in Bitbucket before import, marked as merged by the import user

Added tycho build project

Actually the tests are not executed by tycho as there is no TestPlugin currently, maybe tests should be moved into own TestPlugin?

Based on Eclipse 4.8 photon.

Version increased to 2.6.1.qualifier
