Change your players' names

Today I added the possibility to change each individual player's first name, last name and jersey number.

Other tweaks and improvements:

• Tired defense players should go change if the puck is in the offensive zone
• Tired players should no longer dump the puck wherever they are
• AI passes less often (was getting kinda dizzying)
• Some goalies ended up with a 100%+ saving percentage, so they all got the nerf bat treatment
• Smoother sprite animations
• Removed a weird sound at launch which was caused by the UI initializing
