Bug 14517: List shelves list is broken for translated interfaces

The translation script adds quotes ("") around translated string (Edit
for instance).
Which breaks the json structure.

Example:
"dt_action": "<a style=\"cursor:pointer\"><form action='shelves.pl'
method='get'><input class="editshelf" value="Editar" type="submit"
/></form></a>"

Test plan:
1/ On the staff interface create a private list
2/ Go to More > Lists ('Your lists' tab)
3/ Translate the templates to any language like:
  $ cd misc/translator/
  $ perl translate install es-ES
4/ Enable the translated templates on the sysprefs
5/ Switch to the translated language
6/ Go to the lists page (Mas > Listas in es-ES)
The list should be displayed correctly.

Note: There is a limitation. If a translated string contains a simple
quote ('), it will also break the json.
