hof 6.x-1.0-beta3

Combined release note, since there were two beta releases today:

Beta 2 changes:

Added friendlier names for node types by looking up the names from
the {node_type} table.

Implemented manual setting for site creation date, as requested in
issue #197274.

Beta 3 changes:

Second commit (beta3) attempts to resolve the access bug reported
in issue #347037.

IMPORTANT: After installing BETA 3, you need to run the update.php function as the admin user. This is typically done by logging in as your admin account (the "first user" on the system) and accessing "www.example.com/update.php". Follow the directions on the update function pages, and be sure to select HOF update #1. No SQL queries are reported, but don't panic. This is just a reset of some internal caches, but it is necessary.
