- another failed attempt at gihub integration (via github connector):
 * still defeated by cross domain requests in the second auth phase ...
 * no obvious way to solve this purely client side
- more experimentation and improvements in saving & loading to dropbox
 * thumbnail png files now get correctly saved as binary (and therefore, readable) files
 * for now hacking conversion (see right above) based on pfile.ext
 * loading projects is almost good: all three field of the PFile class instances get instanciated correctly on load, and filled with correct data,
but is very dirty as far as backbone.dropbox goes : perhaps we could set a flag on the models/collections
to signify that we want to get file name/extension content back as individual fields in our backbone object ?
