Merge material-ui-sass project, so both less/sass versions are usable out of the box

@gpbl did a huge amount of good work on the material-ui-sass port. I think it would be a good idea to incorporate his work into the main project. This would have several advantages:

• Makes it easier for end users to choose whether to use sass or less—no need for an extra dependency;
• Whenever the less changes an issue can easily be raised to update the sass versions (rather than going to another project and raising it there);
• Feature parity between the less/sass versions can be maintained more efficiently.

At the moment, the Sass port works with version ^0.5.0. I'm the author of my own Sass framework and I'd be willing to help out in bringing it up to the latest version and keeping it up-to-date once it's there.

👍

Maintaining the port is not as fast as it should, since I wait for the official releases, then go with the diff. If someone adds a pull request to the the sass version is even harder to spot the differences.

I'm a bit slow updating the port to the last release (just moved to a new place :-)) but I should be finished with it soon.

Nice to hear you've been working on 0.6.0 support. The project is moving pretty fast. There's a whole month of changes between 0.5.0 and 0.6.1. Although some of it also seems to be trivial changes, such as changing the indentation.

I think having the two codebases side by side would be beneficial to the Sass port for sure.

@msikma and @gpbl - You may want to keep an eye on this issue - #30 (comment)

If we're able to accomplish this, then less/sass compilation will no longer be needed.
