Finally pushed KiCAD files & garber & BOM to GitHub.

Since the project contains just 2 footprint files as the external dependencies, I decided to copy the files directly in the repo. Using git-submodule might be a better way to manage if there are several dependencies.

If you know how to specify a version (by Commit Hash, tag, or branch, etc.) in KiCAD Library manager,  Plz let me know.

Just for future reference:

• .gitignore for KiCAD projects : https://github.com/github/gitignore/blob/master/KiCad.gitignore
• Renaming tool for KiCAD project : https://github.com/bobc/KiRename
