Remove Gulpfile

Hoping you guys will open/maintain jeet-XYZ repos where XYZ things like Grunt, Gulp, Broccoli, etc.

This repo doesn't seem like the place to support this plethora of tools.
Update npmignore

- rm travis since we're not doing that right now
- rm scss in case someone wants to use the scss version with their node app via node-sass
- add READMEs since docs are avail online
- add tests and CONTRIBUTING since npm installations usually aren't done for testing but rather to simply use the package - tests are for cloning repos
- add LICENSE since it's avail and commit timestamped in the repo
Fix tests

- make section min-height 40
- fix relative path of local jeet
[tests] Add columns to scss
