Address some fo Deuce's observations about the door.sys file generated by sbbs:

- the default protocol (line 27) was hard-coded to 'Y' rather than whatever the user had
selected.
- the "BBS default color (line 41) wsa hard-coded to 14 - now uses the
External Programs (default attribute) value from ctrl/attr.cfg (default: 15).

It's unlikely these changes will actually affect the operation of any doors,
but might as well make the content a bit more dynamic/accurate.
