Use content from another text box not displaying 'copy' message

[Robert Lyon]

Version mahara 1.8

Problem:
The 'If you edit the text of this block, it will also be changed in 1 other block(s) where it appears. Make a copy' message is not displayed anymore if you choose to use content from another text box and have license metadata turned off in the config.

The javascript was expecting to find certain license elements and update their css - but they did not exist in this scenario.

Solution:
I've added a sanity check to only try and update them if the first license element exists.

I've also altered the layout of the instance edit display so that things make more sense - eg keep the choosing of another text box functionality to appear directly below the wysiwyg editor (as it did in previous mahara version)

JS issue when license metadata was not enabled (Bug #1211088)

Also fixed up the layout of the edit form to make more sense
by grouping the choosing of existing textbox to be next to the
wysiwyg editor rather than the bottom of the form.
