Title: Add toggle for double tap gesture between free zoom and screenshots

Set `DSCREENSHOT_WITH_DOUBLE_TAP` to 'true' to enable screenshots to be taken by double tap gestures, instead of simultaneous diagonal corner tapping. This can be useful for single touch devices, such as Kobo Touch, Mini and emulator.
