Move all the files in the "templates/submission" folder.

Rename the "submission" folder to "user". This folder only contains html
templates files related to the "submission" users.

Remove useless variable assignation and user r"" for special logger
string.

This page was useless, and slowing too much the interface and the
server. If we want to open an image for a donor in particular, open
first the donor page, then we can all the information we want for this
donor.

Same commit as a5d12785

This change will offload the generation of the list of all application
related .js and .css files to python (based upon the content of the
'app' directory), and pass the full list, html formatted, to the jinja
renderer.

The new layout is the same as on a tenprint one, the 10 fingers on top,
5 per line, in anatomic order. The palm and writer's palms are at the
  bottom, in order.

At the moment, the upload button is a dummy one.
