Upgrade to instructor dashboard: enrollment, offline grades, remote gradebook

with the way shiningpanda works but I can't see any reason why.

Bugfixing. Refactoring. Removed readonly check for text edits. Styling of text edits with jQuery UI.

Removed unnecessary comments. Added feature to update element either on "change" or on "slide" event.

Fixed bug: jQuery slider default change event name is "slidechange", and it behaves a bit differently than "slide" event.

New feature: Now can specify x-axis and y-axisnames for ticks. Updated "Fick s Second Law" demo to demonstrate this.
