Conpherence - continue the load less quest

Summary: basically makes it so we only really load what we need from the server for any particular update action. the javascript thus then has some things deleted from it. made a spot or two ready for when the pertinent UI won't be there as well. also added a feature in javascript -- updating the document title to the current conpherence title. Ref T2867 T2399

Test Plan: played with conpherence for quite a bit.
