Merge branch 'joomla3' of ssh://git@github.com/Fabrik/fabrik.git into joomla3
Disabled static caching of printURL and emailURL in html helper, as that
causes problems when you have multiple {fabrik ...} plugins, etc.  Could

pretty much done all the "expensive" bits, so may as well just build it
whenever we're asked for it.
