Clean up.

Removed generated files from repo. Renamed /some/ variables and functions
to follow PEP8 naming conventions. Functions generated by
"connectSlotsByName" and database columns are not changed. Also fixed some
spelling errors in the comments.
Reorganization

Reorganized the repo structure. Also split the application into different files. Each window is now its own separate file. Application wide variables are now in the "GlobalVars.py" file.
PyQt to PySide conversion. Python 3 strings.

Converted code to PySide because PyQt doesn't support Virtual Python Environments. This is because it is installed via binary on windows and not through pip. Also changed all "%" based python string formatting to .format() in order to prepare code for Python v3 environments.
