Create per-directory README for our Django apps

[jchristgit]

In the apps directory:

This is the folder directory that I think would benefit the most from some guidance or explanation.

Notable things to point out:

• admin - ??
• api - I guess this is where our api resides. Probably a good point to mention DRF and dive into some api resources
• content - This is where site content goes? Probably good to mention that it’s simple markdown, no jinja or django knowledge required
• events - ??
• redirect - ?? probably don’t need to dive into this
• resources - point out how to contribute resources and the requirements for it?
• staff - ??
