Add the ability to display the profile in a block

This patch provides a sub module content_profile_blocks (It currently only provides one block but I figured it could do more in future).

The block it provides will display the user profile in a block instead of/in addition to in the page of the user account.
The block only works on pages that are user/<uid> or user/<uid>/something as it gets the uid from the url.

There are display settings for the block on each content type that is set as a content profile type (just like the regular user display options).

Patch will apply to 6.x-1.0 or 6.x-1.x-dev.

On a technical note, I don't love the idea of almost duplicating the content_profile_show_profiles() function from the content_profile.module but it was the best way I could think of without modifying the content_profile module.
