adding extra testfiles and making sure that there are no imports that arent already in required_packages

updating the test directories. Will change to the following now; all off the different files in utils more or less get their own test_.py, nothing more

clean up loading of .h files

fix setup.py to not define macros that break .h file loading

Processed alot of what pylint suggested. Might change the naming conventions rules tho, the short parameter names are an issue, but lets not get too strict..

Tried to fully package the core api but that seems like a very difficult endeavour, as passing the shared library via package_data is not enough. it complains about missing symbols, meaning that the other shared/linked stuff is not working anymore. it only works good if things are now loaded by adding this package to the PYTHONPATH atm. will do it later with pip, but thats gonna be some more work
