* Also rename element class to data-table-menu for greater specificity
* Allows us to get rid of a nastiness (DataTable view was binding to events outside of itself) -- and another step to making the Explorer completely autonomous and non-dependent on HTML.
* This also necessitated a nice refactor whereby DataExplorer subviews running off a common Backbone Collection (DocumentList) re-rendering themselves in response to changes in that Collection.
* Use top menu again
* Refactor main area so that data-table-container becomes data-view-container
* Fix up width of flot graph and editor so they line up reasonably nicely
