Renamed source folder and removed crx

The build is now automatically generated with Grunt so it's not
necessary to bundle a copy of the crx file.

I've renamed the folder to better reflect what the source is.
Add README directions for building
Moved core files out of chrome-ext

Want to be able to run builds at a top level instead of nested within
the Chrome extension directory.

Added a fix to stop jQuery Bower installation from timing out.
Second pass on organization and fixes

Updated the build to work again and changed the project structure and
naming to be more approachable for future extension work.
Restructure commit to isolate Chrome extension

This new layout allows various outputs to be created.  In the future
more browsers will have extension APIs and we need to think about
sharing as much code as possible.

I've also removed the old Chrome extension plugin for Grunt as it does
not allow for scattered files to unify into an extension.
Ensure that the build process works correctly
