Merge branch 'rework_analysis' of git+ssh://scm.gforge.inria.fr//gitroot/vidjil/vidjil into rework_analysis

Conflicts:
	browser/js/model.js

Additionnaly we make sure that the name will not have any problem to be recorded (we remove problematic characters)

Two reasons:
1. Easier to have something common in many places.
2. Easier to handle different cases: eg. classic filenames and name of patients (as retrieved from the server).

Since the HTML code including the database_url, it makes sense to comment this JS code too.

The trailing # was not always there, therefore the string was not replaced and
we were not redirected at the right place.

Use a regexp instead that is more general and should catch more cases (wherever Vidjil is installed...)

No need to specify a hard-coded value for the number of sequences.
Fasta object knows how many sequences there are.
