Initial smash-and-paste
Move upgrading into that folder too
Tweak a link and some commands in from_source
Clean up the pre-install page
Add hardware section to 3.6 system requirements
Add new pages to the general Puppet info sidebar
Set default nav snippet
Add rhel 7 to repository instructions
Update redhat-like repo instructions to use symlinked release packages

This is much easier. Haus tells me we're also using configs that let Yum
insert the architecture, so we don't have to have per-arch instructions anymore.
Move preamble out of each repo instructions page
Clean up the EL install page
Remove mention of arch from fedora / EL intros
Clean up the fedora instructions
Add prerelease instructions to el and fedora
Clean up the debian/ubuntu instructions
Several pages: add note about other OSes that I missed
Clean up OS X instructions, remove old skool plist examples

These plists from the wiki were pretty old. I experimented a bit, cleaned the
puppet agent one up, and pasted it inline in the os x install page. The puppet
master one is irrelevant, because you shouldn't be running puppet master with an
init script.
Improve some wording in pre-install
Clean up Windows install instructions

In this commit, I'm kicking out some stuff that's actually reference about
Puppet's run environment on Windows. I plan to reinstate it elsewhere.
Add upgrade instructions to each cleaned page
