Topic page casing

# I'm caught between (a) only capitalizing words which refer to a proper noun (person, place) and (b) using Title Caps on things which have become Things. Gish Gallop falls into a grey area.

# [[rational:Main Page]] -- I added RW to the interwiki early on, when I was going for short over memorable. The full interwiki list is [[Special:Interwiki|here]]. I need to add a note to the wiki page about each site for which Issuepedia has an interwiki prefix... and there's also <nowiki>{{l/rw|page title}}</nowiki> (e.g. {{l/rw|Gish Gallop}}).
