PDF Import Support, Bootstrap 3, Page-layouts, ZODB integration

This release adds a lot of new features, most notably the ability to import searchable-PDFs. I generate these by scanning chinese books that I've purchased into the software. Additionally, we siginficantly improved translation performance by integrating the ZODB database system and enhanced usability significantly by integrating page support, Bootsrap 3, and creating the initial framework for separating out the UI components from the translation components. The next release will complete this separation so that we can target a mobile version in the future.
