Partial Refactor

remove using namespace std, was only used for two lists. 
convert some defines to const int
changed XPTotalPerLevel, and XPTotalDivider to const
Added /xptracker resetonzone as an option
Now uses an INI. Stores "Quiet", and "ResetOnZone" settings between uses. (not char/server specific)
change from using GetTickCount() to GetTickCount64()
Created functions to get output information for percentage of AA/XP for Kill/Total outputs.
Spaces added before/after operators in calculations/assignments.
AddElement now uses long long to match Event member xp and aa instead of __int64
created InitXP() function for setting bases and resetting XP total counts replacing the duplicate code throughout. 
Removed OnDrawHud calls and adjusted to use InitXP where needed. 
removed unused laa/rlaa values from XPAverageCommand
Reduced from creating char arrays sprintf_s to value then passing to WriteChatColor and now use WriteChatf
