Overall simplicity throughout the codebase and unification around Bootstrap 3 (Updated to RC2)

Overall simplicity throughout the codebase and unification around
Bootstrap 3 (Updated to RC2)

MOVED /libs folder within the build folder for compiling of all assets
into tidy app.min.css and app.min.js files. No longer requiring
multiple trips to the server for several files

ADDED app/_/font folder to hold the Font Awesome fonts. This was the
only lib dependency I couldn't move. Naturally, I removed the /font
directory from the font-awesome directory

ADDED new colors to the colors.less file, as well as a reference
swatchs from FlatUI (http://designmodo.github.io/Flat-UI/).

UPDATED build/less/libraries for referencing the library css files as
(less) to compile them into the output app.min.css file

UPDATED index.kit to include the "Basic Grid Layout" from Bootstrap for
reference to the grid system

UPDATED app.js to import jquery.min.js and bootstrap.min.js in lieu of
being imported via libraries.js

UPDATED custom-font mixin to reference "font-" prefixed variables for
consistency with their CSS counterparts

REMOVED libraries.js in order to decrease the amount of trips to the
server for the JS resources

REMOVED	app/_/img/theme in favor of app/_/img - no real value seen over
the past few months -- updated @img-url to reflect this

REMOVED	Font Awesome IE7 support.

REMOVED the margin:0; padding:0; references for h1 -> h6 within the
defaults.less file for inheriting the Bootstrap default margin/padding
