* Update README.md with instructions to use SassC
Updates the Build It instructions for using SassC instead of Ruby Sass
* Updates Makefile to replace Ruby Sass with SassC
This commit replaces the use of the Ruby Sass scss command with SassC's sassc command. Due to the more limited functionality of sassc, output directories must be created prior to running the command and only one file may be processed at a time unlike the many-to-many mode functionality of the scss command.
* Makes import directive relative in _gnome-terminal.scss
This commit changes the "widgets/button" import directive to be relative in the gtk-3.20 _gnome-terminal.scss file which is necessary when using SassC.
* Removes import directive in _gnome-terminal.scss
This commit removes the "widgets/button" import directive in the gtk-3.20 _gnome-terminal.scss file which is unnecessary.
