First stab at a fix - now propertly populating the directive lists.
Handing back to Brad for further work.
Enough of a fix to make the directives tree show sections.  Sections are not parent/child related yet, and categories display incorrectly, and controls do not display anywhere, but this is good progress.
Fixed treeifying for sections
Added viewlink filter for haml and made an example in popover title macro
Fixed category display in tree
Massive speedup in tree view on programs page.  Incremental rendering of subtrees now, when expanded.  Controls/categories/sections/directives all show now
Forgot to save the changes to views/__init__.py earlier.  Didn't seem to be hurting anything but this prevents ambiguity
