Error Printer now prints the debug backtrace for exceptions rather than re-throwing them.
Searching of groups now works when the 'base' parameter isn't available under all LDAP trees.
Learned 'search_groups_by_attributes' action.
'search_users_by_attributes' has learned how to negate terms.

Adding a trailing exclamation point allows negating of terms. For example:

  FirstName!=Adam&LastName=Franco

Would match people with the LastName 'Franco', but who don't have the FirstName 'Adam'
search_users_by_attributes now allows wildcards '*' in the term.
