Sphinx docs
Created by: anaqreon
I created a new folder on the hub web root called "/docs". This contains the Sphinx-generated HTML output of the source files contained in "/doc/sphinx/sources". This output is generated by executing "make html" from "/doc/sphinx/sources" on a system that has Sphinx installed. The current docs were created using Sphinx v1.4 with the theme called sphinx_rtd_theme.
The docs source files are formatted as reStructuredText. The simple text files and syntax should lower the barrier to maintaining and improving the Hubzilla documentation.
There is only some intro content and glossary terms in this pull request, but this way others can begin contributing to the docs on the dev branch.
