Change of behaviour for the save and exit buttons

[Wladefant]

other plugins use the save and close and that seems much more reasonable to me.

Something similar @laurent22 requested:

• Would it make sense to call the Save/Exit button Save/Cancel? Also please remove the icons from these buttons

• I've just checked a few iOS and Android apps and the Save button is usually on the right, and Cancel on the left so please swap the order

About @laurent22 second point, I am not able to see it. Save to the left, close to the right.

I agree with "Save"/"Close" ("Cancel" makes me think of discarding all changes).

Many apps have a "←" back button on the left of the screen. Because js-draw's Close/Exit button does the same thing as pressing the hardware back button in Android, I think it makes sense to put Close in the same place as the back button on other screens.
