Kill the hours menu item!

I thought it'd be fun to contribute to your 2Chez project...so here's my first contribution.

It moves the hours out of the menu and to the front and center of the site. Hours are important enough to not be buried under a click IMO.

But hey, it's your repo, so you can reject this request if you like.

And this was my first time using Sinatra. It took me about an hour to figure out how to run the site...but I learned a few things. So thanks!
