Adds setting to allow user to save the last drawing mode used in Greenshot
so that it will be selected next time image editor is opened.
Also adds setting to config file to allow user to change the default
drawing mode.
Closes#1609
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`
