Rogue Runner v0.7.1 - Updating the Stats

Last update, we got the icons changing. That was the easy bit.
This time, we got the numbers updating. That was also fairly easy as well.

We added some red and green flashes to the number backgrounds to quickly indicate that the numbers were getting better or worse. Down the line I will add indications to the items in the chest so you know in advance if you are making a good decision or not.
I also had to add some default numbers to the character sheet - otherwise, you can't kill anything before collecting a weapon, which wasn't fun.

I've updated the build so everyone can see the inventories now.
