Initial implementation of the openadaptor™ framework including the proper import from PDA travels.

Enable the already existing PDA program for recording travels to work with the new application export / import structure.

Let time records being able to being add to already existing invoices (?? maybe this will be not released due to tax revision reasons ??).

Support for user roles / profiles for all JAAS login modules (at the moment only the standard login module supports this).

Performance enhancements.
