Subject: Parser seperation, progress bar

* Seperated the parser from the downloader code.
* Added a progressbar class, to make it look fancier
* Created some functions to do all the work in downloader.py, cleaner now
* Changed parser.py to htmlparser.py, since it was conflicting with a built-in module
