Revised scraper using ghost.py and either pyqt or pyside -- using qt >= 4.8.4 and latest revision of ghost.py.
If compiling QT from source, make sure all packages are built (especially webkit)

Also updated branch to the latest revisions of origin/flask

pychecker/database initializes the ~6 regexes that we setup
pychecker/views uses scraper.update(url) to load the initial price and screenshot

TODO@ screenshot needs to be cropped or at least sized in the template
