- fixed "delete channels", which were added at the end regardless of the user selection

- changed logic how channel lists can control which columns are visible in the UI
- added column for PcrPid
- removed column AudioPid from SCM lists
- added handling for SCM lists where the value of the "hidden" flag is 255. (Guessing the hidden-status based on another field)
