for themes with compile directly turned off for scss, updated option uses @import for the includes rather than directly via file_get_contents.

Massive cleanup in the export class. Moved all of the export functionality out to other functions so they can be called as needed for clones or sub themes.

General cleanup and renaming _style-vars.scss to _omega-style-vars.scss in all sub themes. This will require renaming file in style/scss and any references to in via @import in other scss files.

Updates to config.rb files to set environments in default Omega themes (omega & starterkits) and themes created by interface.

Setting it to not compile CSS when "Compile SCSS Directly" is disabled, and create an additional config flag to show/hide a warning message when the SCSS compiling is turned off.

fixing issue where unwanted classes were added to #page div. this removes REGION_GROUP--layout classes

Removing block.omega_search as some profiles (lightnight) don't have search enabled by default, and this causes a requirement to fail evidently.

Update to provide basic ability to write scss styles utilizing variables produced via the interface (colors, fonts, etc.)
