Modified build procedure to allow compilation with GHC 6.8:

+ pandoc.cabal now uses Cabal configurations and requires Cabal >=1.2.
+ An alternative pandoc.cabal.ghc66 is provided for those who have older
  versions of Cabal.
+ Debian build process has been modified to use pandoc.cabal.ghc66,
  as a temporary measure until GHC 6.8 gets into debian unstable.
+ INSTALL instructions have been updated.
+ Makefile has been updated to accommodate changes in pandoc.cabal.
+ pandoc.cabal.ghc68 has been removed, since the default version now
  works with GHC 6.8.
