Ever wonder why the lobby menu looks a bit plain, and what that big empty chunk is on the top left?

Added a bit of text to explain that this is a temporary menu, and if the non steam build is detected (i.e. this one!) text appears to indicate that space is reserved for Steam matchmaking. 

Shops now actually tell you what the buy key is, rather than just say "press Buy to purchase". They even correctly tell you the keyboard key or Xbox controller button based on whatever input you're using at the time you walk up to the shop.
