anki: major refactor

This refactoring changes a number of things:

 - use system copies of Python libraries BeautifulSoup, and HTTPLIB2,

 - custom install to avoid installation of unnecessary files and poor
   directory structure, and

 - add patch for sorting out file paths, in particular this fixes
   localization.
