Bugfixes and such

Minor Update here:

-UI fixes, now looks better and more uniform across all screen sizes

-Fixed bug where game would not register that player had died from virus and would be in unwinable and unloseable state

I'm going to be doing  bugfixes and minor tweaks for the next few months.  I'm preparing for a research project where I testing how good the game is at teaching immunology, and a stable build is more important than new features.

Future goals: More bugfixes, updated version available for Linux and Mac.
