+//  DESCRIPTION:

+//

+//  Contains helper functions to handle oscar user capabilities. Scanning and

+//  adding capabilities are assumed to be more timecritical than looking up

+//  capabilites. During the login sequence there could possibly be many hundred

+//  scans but only a few lookups. So when you add or change something in this

+//  code you must have this in mind, dont do anything that will slow down the

+//  adding process too much.
