Add getvideoartwork.com to the available sites to scrape for poster art

This site has excellent quality poster artwork at a resolution of 1000x1500. The best part is that they've been adjusted to get rid of useless text that might have been on the poster (like the opening date and all the credits that are too small to read anyways).

It's my favorite choice for poser artwork, followed by impawards and then themoviedb.
