* Standardize way to fetch node types

Replaced code with profile_generator code (will later re-integrate crud.inc + install_profile_wizard)

Commited first version of Install Profile Wizard. Please note that this version contains a few minor changes with the version posted on Drupal Groups (http://groups.drupal.org/node/5002), the main change being the module name.

Switched to drupal_wiki style menu creation and disabling, #132687 wrapper for node type creation, #133006 get vid, thanks mikey_p, #132686 new user creation, thanks shaber

Had to add next_id check in install_add_format() -- core does fun things with some hardcoded inserts
