Fixed last remaining bprocess unit-test, now more sophisticated tests could follow
Optimized context handling, and fixed a few related issues, now that the code triggers different portions of the code as well.
Made sure plugin-import is actually working at boot time. Improved schema to make clear
there are plugins at boot time, and those at program time.
Adjusted license information - bcore is now LGPL. Still missing to adjust headers in every file.

Additionally, a test for plugin-loading was added, which revealed yet another issue that still has to be fixed.
