Call a custom system command when receiving a hilight.
Originally based on hiligthwin.pl
by Timo Sirainen, and djcraven5's idea for
making remote computer beep through ssh.
Example of use, assuming you have ssh and beep on your remote:
/set hilightcmd_systemcmd ssh user@host beep &
The hilighted text may be passed as a quoted string:
/set hilightcmd_systemcmd printf "%s\n" %(message)s >> ~/hilights
