Templates prepared for django 1.5

In django 1.5, {% url module.method %} must become {% url "module.method" %}.
For this to happen seamlessly, from django 1.3+ a new directive has been
introduced, named "{% load url from future %}"

This commit includes this afforementioned syntax into every(hopefully..)
template and also changes the url stanzas to the new syntax.
