PEP8 fixes!

I opened the files with my vim and PEP8 checker. 
I fixed most of the errors (except for E127 and E128).

I couldn't start the debugger, so this needs to be verified! (please tell me how to do it).

I found this error on qdb_launcher.py :  
geditpydebugger/libs/qdb_launcher.py|7 col 9 error| undefined name 'test' [F821]
