Feature request - Add option to translate DEL to BACKSPACE for external doors

Some native unix applications, such as Zmachine emulators only accept Backspace (ASCII 8) as a backspace key, however some terminal emulations send DEL (ASCII 127) which confuse the native application.

Would it be possible to add a configuration within an individual door such as "Translate DEL to BS?" which would be "No" by default which could be changed to "Yes" for problematic doors?
