MQ2DPSAdv - Fix issue with MyName not changing

• MyName would only get set if the plugin was initialized while in game
• Add name setting on game state change instead of just on plugin load while in game
• Remove using namespace std
• Remove DPSDEV since there is a command already that could be overloaded
• Remove unused items from header
• White space cleanup
• Magic Number cleanup
• Minor formatting changes for readability
• Changed capitalization
