Decision and possible cleanup regarding front-end

[inaimathi]

Right now, we've got three separate pages being maintained in the front-end. If we wanted, we could collapse those down to a single main.js instead of having separate tree-view, query and search sub-folders.

PRO: No more messing with the project.clj file when we put in a new javascript page section.
CON: Heavier javascript load on each JS-enabled page, which will grow with each piece of functionality we put together.

Not sure how bad the CON really is, because I get the sneaking suspicion that we might be headed towards a single-page-app model at some point in the future, but I have no idea how soon that might be or if we're actively thinking about it.
