Updated the UI

I've updated the UI since the last release, and laid the foundations for an upgrade system. Firstly I will have to add a currency system, for now I'm going with the good ol' classic gold coin - with which the player will be able to use to buy upgrades. Also made a new level two ship sprite which is being used as a placeholder as of now.

I won't update the downloadable until release, though.

Without further ado, here's the new title screen.
