Add CONTRIBUTING.md

Add a CONTRIBUTING.md file to each repo that links to either the DoneJS contribution guide ([coming soon!](https://github.com/donejs/donejs/issues/295)) or a more specific one (e.g. the CanJS contribution guide for a CanJS project).

If there’s already a contribution guide in a repo’s README, then move it to CONTRIBUTING.md and format it similarly to the DoneJS contribution guide.

Otherwise, you can use the DoneJS contribution guide as an outline for what should be included. You can look at related projects to see how their templates were customized and here are some example commits that show updating a project to meet these guidelines:

- [donejs-firebase](https://github.com/donejs/donejs-firebase/commit/b1e4d0b282d8e5277e04875d5378ee7e787e8fcf)
- [syn](https://github.com/bitovi/syn/commit/38d515a4d186badea4e2909437cdde0eab95c698)

Of course, if you’re unsure, please reach out to ask questions or open a PR anyway and we’ll fix it in the review process. Thank you for your help!

Below is a list of all the repos. Check off the repo once you’ve submitted a PR for it.
