Conversion from LESS to SCSS
The supported stylesheets in Horizon have been converted to utilize SCSS rather than LESS. The change was necessary due to a prevalent lack of support for LESS compilers in python. This change also allowed us to upgrade to Bootstrap 3, as parts of the Bootstrap 3 LESS stylesheets were not supported by existing python based LESS compilers.
