- Sony Android (E-Format) now supports independent favorite list ordering

- fixed issue when saving Sony Android list with high program numbers (causing negative int32 values due to bit shift)
- for unknown DVB service types the UI now shows the number instead of an empty string
- loaders are now setting the OldFavIndex (to be consistent with the use OldProgramNr)
- Form shows full file path in title bar
- no longer defaulting to "swap" mode when opening a file and using "current order"
- show "Source" column in the left list when editing a mixed source favorite list
