Dawn of Light Source code

- Correct weight and value for stackable item
- ThrownWeapon now work

- Enable second level cache where needed
- Add UseReflectionOptimizer in serverconfig to easily disable it (fast server start but bad runtime performance)

- Add isDiving flag and diving timer / damage

Use uint for tick to avoid Environment.TickCount negative overflows (Noret fix)

New spawn generator system
Add DelveString method in Item / ItemTemplate class
Add PeaceBrain and remove eRealm.Peace (a peace brain does not think, and never attack). This new brain type must be used by all peace npc like quest npc, merchand, stable master ect ... Don't forget with this brain your npc will never fight !!! ... The main adventage is a low cpu usage because this brain never think.
