Allow pycicle to take its per project settings from the source project itself.
Each project that uses pycicle for testing can have a pycicle subdir that stores the testing/config settings, the main advantage being
- The settings for the project can be maintained by the project owners without modifiying pycicle
- Different branches could (in principle) have different test settings
- Changes to options can be smoothly updated by the project
and lots more reasons
