Changes for Version 2

Based on some early feedback from Dan and a couple of my coworkers, I've done a few quick updates.

• BUGFIX: Last run isn't showing after visiting the gear page
• FEATURE REQUEST: Volume controls
• Remove the distinction between molds and starting molds
• Change the unlock for the mop to 200 molds
• Clarify that the unlocks are based on All-Time achievements on the gear page

I've also made the menus scale with screen size, which provides a more uniform experience there.

Last but not least, I've added a small description of "turn based" to the project page. People weren't finding it clear that the mold was spawning based on your movement and attacks, so hopefully this helps clear that up a bit.
