Install Bower package on init
Moved bootstrap themes to @scotch/bootstrap-less-themes -- it's now a component.
Ignore vendor directory
updated dependencies to latest
Removed SASS SCSS from automatic compiling list. SASS support can be added by adding the 'sass-bruch' dependency to your package.json file:

    "sass-brunch": ">= 1.5 < 1.6",

It was removed because it requires the sass gem, therefore users would have to install both ruby and the sass gem before they could proceed.
