wellington formula

Hi, I would like to add the wellington project to brew.  I'm new to building formulas, so any help would be great.  I noticed that go get ./... does not work well with brew.  I took tips from the other go projects to explicitly require all packages as go_resources, including the main repo which has 5 packages in it.

Questions:

* This formula is dependent on libsass which requires compiling c code, did I properly mark that requirement?
* I'd like to alias this project to `wt` which is the name of the cli tool, how is that done?
This denotes an option to build with C++11 support; it looks like wellington is all Go and C. What were you trying to do here?
