Fix adding a relation to a document with special characters in title

It seems some generated javascript in relation listing is badly escaped.
Some utf8 chars seem to cause a problem, but using a single quote in a document title always causes it.

Steps to reproduce:
1. create a Note titled "Ted's stuff"
2. Open a second document
3. go to relations tab
4. Search for "Ted" and click the result's title

Expected:
the popup should close and fill appropriate form fields in the relation form

Actual Result:
Nothing visually happens. Under firefox, the following javascript error is raised
missing ) after argument list
updateParent('5817a599-ca8e-4523-8995-33ed8261bf2f', 'Ted/'s stuff');

Also I guess JSF seems to be doing some double escaping javascript-breaking, escaping on those links which results in things such as this:
<a href="javascript:updateParent('15c8b1cb-f3eb-455a-bca1-0dd5b45093fe',%20'R%E9gie%20des%20rentes');">Régie des rentes</a>
those javascript expressions won't work until the urlescaped elements are removed or unescaped

Reproduced under firefox and chrome
