## Detailed Description of the Pull Request / Additional comments
Adds option to choose from 3 click behaviors for each standard mouse
button:
* **Pick color and open editor**: Copies color to clipboard, saves it to
the color history and opens the editor
* **Pick color and close**: Copies color to clipboard, saves it to the
color history and exits
* **Close**: Closes color picker without copying the color
Pressing <kbd>Enter</kbd> or <kbd>Space</kbd> does what clicking the
primary button would.
Left and middle click actions execute on mouse down, right click on
mouse up for reasons discussed previously (I can't find the conversation
now)
Default settings are chosen in such a way that very little or nothing
changes by updating.
