Introducing a new constant INFINITE_TICK
Changed current usages in items, npcs and source to use the new and correct constant.
Replaced some invalid usages of INVALID_TIMER and replaced them with the new constant.
* Created setter and getter functions.
* Adjusted all calls to use these functions.
* Converted mapflags to C++ map container.
* Converted drop_list to vector.
* Converted skill_damage ERS into vector and increased limit from UINT8 to UINT16.
* Cleaned up several functions to be more dynamic to reduce redundancy that was all over the place.
* Renamed nosumstarmiracle to nosunmoonstarmiracle.
* Adjusted skill_damage mapflag to use proper defined constants.
* Refactored map index into a vector.
Thanks to @Lemongrass3110 for a lot of help and @secretdataz!
* Alphabetically sorted includes.
* Updated copyright and license text to match across all files.
* Removed pragma once define in header files in lieu of ifdef guards.
* Initial progression of moving the map-server to C++ format.
* Converted all core files to .cpp and header files to .hpp.
* Refactored the refine database parser to utilize native YAML C++.
Thanks to @Jeybla and @lighta for their help!
