Implement Level Timers and Anger Timers

[AddisonG]

The variance of dinosaurs and other creatures spawning is the first factor that determines difficulty as time progresses, also known as dinosaur level. The second factor is the dinosaur anger, which increases dinosaur move-speed, attack-speed, and health regeneration.

The dinosaur level dictates the types of dinosaurs that are allowed to spawn. Level 0 dinosaurs are meant to be minor threats that keep survivors on their toes, but little more. Higher level dinosaurs will be major threats that may require a few players to take down.

Because there will be quite a big gap between the increasing of dinosaur levels (due to me not wanting to make 20 sets of dinosaurs for each level, so that difficulty scales nicely), there will be a second timer which increases the dinosaurs anger, every minute or so. This will just be a global aura, which affects all creatures.

I've made the first 4 levels of dinosaurs, and the level timer is fully functional. As I add more dinosaurs, there will be more levels. As it stands, the game will probably stop spawning dinosaurs after it goes beyond level 4.

The anger timer is ready for when I decide to start work on properly altering the global-aura on the anger-dummy. But the ability for anger has been created, so that won't be hard.
