[web] Stop patching jquery.treeview.js
This logically reverts part of e9b7cd2e9012 "allow treeview to work
correctly in a tab #345293".
The treeview and ajax code have suffered a number of changes since then, this
change doesn't seem to be necessary anymore. It is most likely unneeded since
f65208c9dbdc "[javascript] use jQuery.one('ajax-loaded') instead of
jQuery.bind() in add_onload to avoid multiple callback executions".
Schema of the data
------------------
First take a look at the data schema_ then try to remember that you are browsing
through a heap of data by applying stylesheets to the results of queries. This
site is not a content management system with items placed in folders. It is an
interface to a database which applies a view to retreived data.
