Theme tweaks for YOSPOS
Fix crash listing thread with no thread tag.
Fix crash restoring open private message view.
Formatting.
Bump version to 2.0.2.
Fix weird ordering/disappearance for FYAD posts.

FYAD posts don't have the "data-idx" attribute on their <table> tags, so they
fall back to the default. Unfortunately, the default was poorly calculated to
start at zero, not one. Fixing the default restores the proper post order..
Adjusted NSURL+Awful to accept archives.somethingawful.com addresses

Archives URLs are treated like forums.somethingawful.com urls, so hopefully that generally works
Themeing changes

Navbar in dark theme changed to blue, blockquotes / pre / code stylings
changes, mentioned fixed in dark themes
Add back button on iPad when following links within Awful.

Temporary fix so people can get back to the thread they started at after
tapping a link to some other post/thread.
Abbreviate thread list titles and empty their back button.

Long forum names don't fit (and you probably got to it from the Forums list,
which shows the full name), and the back button works just fine as a bare
chevron.
