Add thorough documentation for the djblets_utils template tags.
Review Request #7738 — Created Oct. 25, 2015 and submitted — Latest diff uploaded
djblets_utils is one of the oldest modules in Djblets, and its documentation was really lacking. This change fleshes it out, bringing it up to current standards, and adds examples showing how to use all the tags. This started off as some cleanups to appease Sphinx, but ended up becoming a complete rewrite of the docs.
Built the docs and read through them.
