Subject: [PATCH 1/5] Add sequences and signals for desktop notification

Add sequences
  OSC 777 ; notify ; SUMMARY ; BODY BEL
  OSC 777 ; notify ; SUMMARY BEL
  OSC 777 ; notify ; SUMMARY ; BODY ST
  OSC 777 ; notify ; SUMMARY ST

that let terminal applications send a notification to the desktop
environment.

Based on Enlightenment's Terminology:
