Merge 'About' and 'System Info' items in main menu

[rien333]

Thanks for your continued work on Plato!

A little nitpick-y, but I noticed that the main menu (the bars in the top right) is quite cramped, especially in landscape orientation. I've also noticed that the 'About' and 'System Info' items offer similar functionality, but that the 'About' item only displays one line of information (i.e. Plato's version number).

The 'System Info' item is really handy indeed. But wouldn't it make more sense to have Plato's version number also included with the rest of the hardware, firmware, and software details? Merging the 'About' and 'System Info' items in this manner would make the main menu less crowded. And is there a sharp difference between 'About' and 'Info' anyway?
