Reverse sort order for resolution date globs

Sphinx 1.5 and later allows a :reversed: parameter for :glob:
toctrees. Since we're presenting our resolution index in reverse
chronological order grouped by year, reversing the glob order keeps
the dates within each year consistently ordered as well. Yes, this
is probably me being OCD.

The SIGs governance resolution file was inconsistently named,
leading to it showing up outside the expected sort order. Rename the
file and add a permanent redirect from the old URL to the new one.

Related cleanup, the main index toctree was incorrectly marked as a
:glob: even though it didn't use any wildcard patterns so has been
corrected.
