Minor fixes

[p]Fixed some issues with Chording and Resolution settings, as well as the tutorial screen. Chording is now done just by left clicking, as it is in OG Minesweeper.[/p][p][/p][p]I've changed the activation zones slightly for hotbars to try to stop them getting in the way in some situations.[/p][p][/p][p]I'm still working on diagnosing some saving/loading issues as I'm having trouble replicating it myself. Will push a patch as soon as I identify and fix it.[/p]
