Patch for Profile integration

Adds section to settings to choose profile fields. Profile fields must be 'Public field, content shown on profile page and on member list pages' (see profile field settings)
Outputs to table theme not user_list theme for css themeing (still needs work, not pretty)
Expands User data objects returned for possible additions of columns like user creation, last loged in, avatar/picture, etc.
Includes Roles integration patch

TODO:
Code needs cleaning formating, but it seems to work PHP 5, mysql 4
must refine to handle data types
Thinking about adhering to profile module permissions and using module functions
using Cache might be smart too
