Upgrading to the latest version of jQuery/UI

plus.click({}, function() { }); was causing errors, they
were fixed by a new jQuery version.
Moving back to the "source" element

Attempting to lump in the source element with the clones
was a bad idea, since the clones are not dynamicForms
(and even if they were, they'd have a completely
different copy of the plugin, so message passing would be
out). Having a centralized and standard launching-off
point is not that bad, I do wish this was more
generalized though.
Making plus/minus buttons work for source element
Adding "addAfter" parameter to add
Binding to clone +/- buttons
Adding functional remove
Cleaning up index.html a bit
Adding support for "external" +/- buttons

External +/- buttons are +/- buttons that are outside of the template
