Copied code and graphics from download dialog to radio settings tab.
Nothing has been removed or touched in the download dialog.
Absolutely nothing is functional yet, but it compiles.
Scrapped first move attempt. To much work to do it this way. Will try a more direct approach.
AppPreferencesDialog is done. All firmware settings can now be selected, since the horrible, horrible code from downloadDialog has been integrated.
Next step:
Remove fw selection code from the download dialog and instead display default firmware name.
All firmware selections have been removed from the download dialog.
A consequence is that it is always possible to try to download voice files. Even for those boards that have no voice capability. I do not think that is a big problem. Anyone trying to download voice files for a unmodified 9x should not be surprised to get a "file not found" browser message.
