* Fixed logic so that when a user is adding a node (/node/add/node_type), the user's theme is used if the node type is among the allowed ones.
* Added setting: which node types should use the users' theme? Beside 'blog', you can add any CCK or custom node type.
* Added setting: should a user profile page use the site's default theme, or the user's theme?
* Added a setting page, for the three items listed above.
* 34360: separate the blog theme from the site theme.
