Title: add target_project_id to create merge request

Make it possible to create a cross project merge request using the API.
Gitlab supports this from at least version 6.0.1 (what we are currently running).

I added the parameter as the last one for backwards compatibility, however next
to $project_id would make a more logical order. If you would like a change from
the current pull request, please let me know.
