Don't pull deleted links for review.
Switch to sscgi library and major refactoring:

 - Got rid of App monad. Replaced with implicit parameters and template haskell/unsafePerformIO.
 - Reduced the number of modules by eliminating them or combining them.
 - Got rid of Member.Auth module (it was only broken out from Member to break an include cycle).
 - Got rid of the out-of-date handbook.
 - Switched to using cabal-dev.
 - Got rid of article management functions (just looks things up from the DB now, the rest can be moved into scripts).
 - Made all errors bounces (error message through cookie, displayed by javascript) instead of plaintext responses.
 - Mostly switched to creating ToJSON/FromJSON and ToMarkdown instances rather than custom functions.
 - Updated to a newer Blaze HTML library.
 - Got rid of all regular expressions (mainly by getting rid of the Gravatar library and generating the md5 hash ourselves).
 - Made all Page functions pure.
 - Made some changes to get it working on a Debian server.
 - Surely more changes I've forgotten...
