Download an archive of project files

[wapcaplet]

For projects that are created on the RTD site (as opposed to those that are imported from a repository), it might be nice to have an option to download an archive of all that project's files.

Use case: I start a new toy project, and throw a few docs up on RTD. But then the project grows, and now I want to grab all my docs and put them in my repository.

This is already implemented at the bottom of projects.views.private, but not exposed in the UI. Could probably be done in the dashboard submenu optionally for people who have non-imported projects.

Heck, all the work was done for me. I added it to the project bar, next to "Manage Files": wapcaplet/readthedocs.org@0d36c59

One wrinkle is the call to os.system in the view; it should work to use Python's builtin zipfile library instead. I'll look into it.

Switched to the zipfile library: wapcaplet/readthedocs.org@3402dc2

This was fixed.
