gui.py: one button per direction, "SAB file to SAX file" and "SAX file to
SAB file". The button decides which extension the chooser offers and which
way the conversion goes. The log names the chosen file and its folder before
the work starts, then the output file and folder when it finishes, each value
on its own line. Output lands next to the input under the timestamped name,
so there is no save dialog and nothing is overwritten. Sedona home sits at
the top with a Change... button that validates manifests/ and rewrites
system.properties.
run.py: no arguments opens the window, any argument goes to the command line
converter. pythonw run.py for a shortcut with no console.
config: NAME/VERSION are now "SAB - SAX Sedona Files Converter 0.0.0.002",
carried by the window title, every dialog title and the CLI banner. Adds
choose_sab_input() - the existing choose_sab_file() is the save dialog.
