Alpha 25.1 Released!

This release is mainly to deal with some bugs and areas for improvement in the menu system when using it with a mouse and keyboard. I also snuck in some very minor improvements elsewhere.

Alpha 25.1 Changelog:

• It's the first minor version!
• Menu buttons will interact with the mouse again
• You can navigate the menu with WASD again
• Escape key will back out of menus or pause the game if already at the top level menu
• The Aerolab menu is grayed out if you don't have any technology
• Some players were not getting shadows due to incorrect default quality settings. There is now only one quality setting, what used to be known as "Radical".
• There's a pretty animation showing how much of your hitpoints you've lost when you get hit
