Non-filtered PMs do not alert using flashes

I think the issue is that, rather than letting mirc send output to the default window and flashing etc. according to mirc settings, instead we sometimes redirect the output to a different window using echo (in DLF.Win.Echo) and we probably need to add logic to add the correct flags to the echo to mimic mIRC's own flash/beep approach.

Which means we have to understand mIRCs logic based on relevant mIRC settings, and then replicate it.
