Currently Congress specs sphinx doc build broken,
all of the rst files can't be built into html files,
so previewing the html format of specs is impossible.
Fix it so that we can review specs in human readable way.
Some format issues exist in current rst files, so fix these
at the same time so that tox py27 and docs build can pass.

Include file name for specs with missing subtitles. Include file name for specs
with docutils errors. Removed empty file.
Formatting errors fixed in specs:
* Line length past 79 characters.
* Consistent capitalization of subtitles (first word only, which was the
majority of the existing ones).
* Missing subtitle.
* Unexpected indentation.
* Title underline length too short.
