Experimental 'One-Button' Mode

Hey all - so two thirds of the gamejam judges apparently weren't as familiar with 90s Revolution Software titles as me and thus couldn't intuit that you had to right-click to examine objects. Not only did this halt them from solving some puzzles, it's also where, like, 60% of the jokes are in this genre! Oops.

To combat this I've implemented an experimental 'One-Click' mode that you can turn on/off manually from the settings, it switches out using both mouse buttons for a Curse Of Monkey Island-ish verb coin. I *think* it lets you do everything the old system did but it needs some robust testing.
