(DOCUMENT-27) Mention removal of Puppet::Util.symbolize in Puppet 3.0 release notes

We missed this one!
(DOCUMENT-30) Clarify interaction of virtual resources and run stages

Virtual resources are evaluated in the stage where they're declared,
not the stage where they're realized.
(DOC-609) Change Hiera complete example to use YAML instead of JSON

Most of our users are using YAML because it's easier to write by hand, so our
examples should prefer it.
(DOCUMENT-58) SSLRequire is only valid in a directory context

You can use SSLRequire in a "location" container, but not bare in a virtual host
container. Cf. the following:

http://httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslrequire
http://httpd.apache.org/docs/2.2/mod/directive-dict.html#Context
(DOC-734) Add instructions to install json gem on os x 10.8 and earlier
Align a bunch of arrows
(PDB-608) Prepare PuppetDB indexes for 2.0.0-rc1

This creates the new index for PuppetDB 2.0.0, it also fixes some
obvious typos with both this index and the master one and configures the
git download process to obtain the docs soure for 2.0.0 from the pdb
stable branch.

- CNs don't have a uniqueness requirement; my bad.
- What with current motions toward OCSP stapling as the standard, we should
  mention other means of revocation checking.
