Allows Mac OS users to contribute without adding DS_store files.

[HunterEl]

GOAL:
Allow Mac OS users to contribute to this project without accidentally adding DS_store files.

CURRENT:
Currently, your .gitignore is very comprehensive, but I couldn't help but notice that it excluded some Mac OS specific files. Mac OS users are fairly large portion of the GH open-source community and it would be great if they could contribute without adding unnecessary files.

IMPACT:
This will allow for a smoother dev experience for theMac OS community.
