Subject: [PATCH 1/6] emulation: 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:
