Brian ee88e25b2f Update Greenshot to latest version
Greenshot updated from 1.2 branch at commit
e9ab99c5acc99785cc5045b4b5493c9b6504d016

This solves #1341 and #1079 for allowing support high DPI monitors.
Additionally, the following were implemented:
- #748 - Objects can be saved to file and loaded from file via menu
- #676 - Keyboard shortcuts added for 'Save and close' (Alt+S), 'Close'
(Alt+W), and 'Close and cancel tasks' (Alt+C)
- #1189 - Editor opens sized to image. Can be disabled via Greenshot ini
with `MatchSizeToCapture=False`
