comms/morse: update 2.5 => 2.6
- Switch to Gitlab upstream
- Use textproc/xmlto for man page generation
- Format using portfmt(1)
- Actualise patches to current version
- Use explicit localbase:ldflags helper for X11 option instead of CFLAGS and LDFLAGS
- Regression: build with X11 option set failed with: ./alarm.h:15:15: error: a parameter list without types is only allowed in a function definition
