Long description field gets mangled symbols

For some reason, when the platform copies the object description to the edit box (restructuredtext), symbols like < (typically used inside URLs in restructuredtext) gets translated to < and is displayed as such. If the user tries to save the text, he/she will get an error in a place typically unrelated to the change.

How to reproduce this problem:

1. At http://beatweb-staging, fork the algorithm tutorial/linear_machine_projection/5
2. Scroll down as to edit its documentation. It shows:

The linear transformation relies on the `Bob <http://www.idiap.ch/software/bob>`_ library (version 2).

Whereas it should show:

The linear transformation relies on the `Bob <http://www.idiap.ch/software/bob>`_ library (version 2).

I guess we're escaping too much somewhere.
