Title: Added option to include responsive styles via LESS variable

Set `@responsive` variable in `variables.less` to `true` and `responsive.less` will be compiled into `bootstrap.css`.

Alternatively, set the variable to `false` (default) and everything is as before (i.e.: compile `responsive.less` yourself or don't bother at all).

This pull request is based on issue #2796. I finally got around to making my own fork so I could create pull requests instead of being lazy! :)
