Update 0.8.3.3 - Hidden cursor fix

[h3]New features:[/h3]

Software cursor is now a opt-in option in the options menu. As players reported back that windows hides the software cursor for some specific resolutions and screen scaling settings in fullscreen mode the software cursor is now disabled by default. This should always yield a visible cursor with the option to activate the nicer looking software cursor if your windows settings support this.
