Added a man directory and a jekyll.1.md.
Jekyll --help now loads a man page.
Logic to find and load man file.
Gemspec updates for md2man install when > ruby 1.9 is available.
I put my version logic in the wrong spot.
Initial commit of officially formatted man pages.

tries to make it so md2man installs only on 1.9
makes sure not to require the md2man rake file if we haven't installed
adds missing brackets
fixes all man pages to match latest jekyll
