Lazy-load list of textboxes when opening textbox form (Bug 1393734).

The query to load other textboxes when displaying textbox config. forms
is very heavy in a large instance of Mahara. This patch postpones the
listing of other textboxes in the textbox config. form, until the link
to display them is clicked.
This enables the textbox config. form to load and display quickly.

TODO: optimise loading speed of list of textboxes. This process is still
as slow as it was before - all this patch does is defer it until it's
actually required!
