Cleaned some spacing.
Edited README for Python3 related stuff.
Removed pydl-ui.py as we'll worry about the GUI in another branch.  Edited a few mistakes that weren't caught when written for Python2, cleaned up spacing, edited setup.py to match current requisites for Python3.
No need for urllib3 as Python 3 comes with urllib as part of the standard library, changed to urllib.  No errors in the IDE, time to test.
Fixed outdated download code.  Single file downloads via the main loop now work as intended, as does the progressbar.  The 'special download' methods were updated with these changes but have not been tested.
All functions/methods have return statements, amended docstrings, added quit option to query.
added gitignore
rm .idea from project
