Unresolvable dependencies (version bump of #191 and pandoc)

[neitsab]

Seems like there is some discrepency between haskell-core and -happstack (probably explains #191):

:: Synchronizing package databases...
 core is up to date
 haskell-core is up to date
 haskell-happstack is up to date
 extra is up to date
 community is up to date
:: Starting full system upgrade...

warning: cannot resolve "haskell-pandoc=1.14.0.4_0-3", a dependency of "haskell-gitit"
:: The following package cannot be upgraded due to unresolvable dependencies:

:: Do you want to skip the above package for this upgrade? [y/N] y

While https://github.com/tensor5/haskell-happstack/commit/724955c25ca2fe278b194974ad8331ea4fa76fae touches missingH, css-text, pandoc, gitit...

Only [haskell-core] is maintained in this repo, so it's much better to report this to the maintainer of the happstack repo.
