Migrate build system to gradle

Basically we should replace the old tritonous libraries since non one ported them into maven repositories. Right now we are not sure if there is a valid replacement library. I found some libraries from google but they did not work. Right now however the gradle project just build well and runs without problems also with the old libraries.

removed useless dependencies for tools.

moved "data" and "distribution" directory into the freelods subproject

Fix to test because it did not remove the working directories correctly after test run.

removes useless logs.

Fix at the gradle scripts now all projects compile.

Created subproject to let compile also the tools and removed deprecations from junit and more little fixes.
