Keyframes Rehashed

This is an unsolicited redesign of Keyframes, a new design, animation, art and science community. Here are the details of my redesign:

* Drawn according to 8pt grid
* Tightened up logo
* Left-aligned menu
* Added text shadows for consistency with UI shadows
* Added subtle gradient on header bar
* Added inner shading on toolbars
* Made input visible as an input
* Added button to activate/send on the input
* Inverted chat sidebar BG for increased contrast
* Redrew upload icons for more consistent weight and decreased size to increase content area
* Tightened letter spacing on star count
* Adjusted font styles and colors
* Other things...
