Add devframe docs

[fnoop]

Add environment to fork/contribute to devframe docs

[fnoop]

Steps to contribute: Set localconf param eg. "maverick_web::maverick_docs::devframe_docs_gitpath": "https://github.com/fnoop/devframe.git"

rm -rf ~/software/devframe_docs
maverick configure

This sets up a named fork of the devframe repo, compiles the jekyll dependencies, compiles the docs and serves the through nginx endpoint (/web/docs/devframe).
