Styling changes, prototyping for data clipping, and table sorting feature.

Relates to some issues, but mostly just styling.

Note: This pull request isn't associated with any given issue, and is more of a styling and code structure pot-pourri.
Sets up the structuring for data filtering in the guise of #413.

Important: I updated jqGrid plugin.

Also: I renamed "Full Data" to "Show All Data", and "Advanced Tooltips" to "Detailed Tooltips".

As far as testing goes, I'd try to save a visualization using the new searching operators and see if they persist.
