Title: add git commit information on manual's cover only if in Git repo

Hi,

With this change I propose to add git commit information on the cover of Prawn's manual only if we are in a Git repository, i.e., if a .git directory is found in ../.., relatively to manual/manual/cover.rb.

Cheers,

Cédric
