altosui: Improve configuration save feedback

Mark window title as (modified) with any unsaved changes. Disable the
'Save' button while the save is happening. Wait for the re-load of
configuration values before clearing the '(modified)' state. This lets
you see when the flight computer has accepted the updated values.
