Limping in to the finish line... remove non-functioning buttons from control panel (and fix central server coach reports!)

Two small changes, both to address the last unimplemented 0.10 issue:
* Remove buttons from control panel, which never functioned.
* Rather than remove coach reports links, make a simple change to include "endjs" in all of our templates, so that coach reports work.  (NOTE: this is a temporary change, as "bodyjs" and "endjs" will be deprecated as of #235)

Testing:
* Tested to make sure that buttons disappear (they do)
* Tested to make sure coach reports work on both central and distributed servers (they do).
