Write SASS Code

[danpastori]

Problem

Shr only supports LESS, I'll write SASS to be used along with LESS.

Rationale

Really just another option for compilation. I happen to know SASS and can structure
it the same way that you have your LESS structured so other devs can contribute as
well or use in the situation they have their application written in.

Solution

I'll write the SASS code for Shr.

Pros of Solution:

• Another option for users who may be using SASS instead of LESS

If you'd like to move forward, let me know and I'll submit a PR!

I'd be happy to drop LESS support in favour of just SASS. 👍
