Bug 12032: disable automatic URL conversion by TinyMCE in news

To test:

* create a news item with a link in it that is within the same domain

example: my koha was at http://demo.mykoha.co.nz, I created a link in a
news item to http://demo-intra.mykoha.co.nz

* note that when the item is saved, the url changes to ../../../../ (or
something like)

* apply the patch

* edit the link again, and save it

* note that the link is saved correctly
