Update GHC 6.8.1 notes with my observations;
Add myself to AUTHORS;
Add my favorite book series to READTHEM;
Revamp the Pugs.cabal.in. This includes formatting, additional metadata, and adds a dependency on a more recent bytestring (to work with all the preceding patches), and also a Cabal, because we need that oldtime section syntax... for compatibility with GHC 6.6 & 6.8
Remove a regexp from util/build_pugs.pl because we can't have backwards compatbility with that old Cabals if we want 6.8.x as well, so it merely messes up the generated Cabal file.
