CodingStyle: review allowed prefixes

 - Use TypesTool methods instead of looking in modules __dict__ when
   possible.
 - Allow prefixes from mixin
 - Allow prefixes from interfaces without the I ( ISomething ->
   Something )
 - Allow "Zuite" and "ListBox" that are used in zelenium tests.
 - Allow "DCWorkflow" that is used in some workflow scripts.
