Libra - organize your stuff, beautifully.

The following bugs are fixed in this release:

1. Amazon returns incorrect large physical sizes for some items. This resulted in other items having a very small size that approaches 0, which then crashes the rendering. This condition is now caught.

2. DVD's now ignores the physical sizes returned from Amazon. The aspect ratio is still respected though.

Enhancements:
1. Added the ability to import generic text files (can be CSV text files as well). Like its generic Excel counterpart, this works by detecting UPC/ISBN/EAN codes within the text file.
