WIP: InfoPros docs rewrite [skip ci]

Work in progress. Please do not merge.

Note: Check changes to conf.py.

Otherwise, follow standard InfoPros rewrite procedure-- complete review, merging in changes made since the InfoPros forked the docs, redirects, and so on.

@chdoig I believe this is ready to commit, and want to be sure it's okayed by a project manager. Havoc did most of the Anaconda Project docs but is now just consulting. Would the best person to approve this PR be you, perhaps Ben Zaitlen (#2 contributor to this repo), or someone else?

[electronwill]

Thank you!

@chdoig can you please grant me admin access at https://readthedocs.org/projects/anaconda-project/ so I can add these 5 redirects?

[electronwill]

Done. All 5 redirects made and tested. Thank you, Christine.
