New title logo and gameplay updates

Hi all, hope you're having a great weekend!

I've uploaded a build with the new title logo that I've drawn over the weekend, and also some gameplay updates. I decided to change the name of the game to Seismic Warning, as I think it's a cool name that matches the game theme without sounding generic like Drill Masters. Take notice that the how to play dialog is outdated and doesn't match current gameplay from the latest build. The how to play dialog will be updated once I rework the main menu, and it will be called "the drill masters' manual".

Have fun!
