[FEAT] Ecs: Updated uncached table-matching algorithm to use stack algorithm instead of recursive calls

[WIP] Ecs: Creating a unified Ecs interface for staged (deferred) worlds and unstaged (immediate) worlds

[FEAT] Serialization: entity deserialization with rapidjson, fixed sdl regenerating headers on every build

[WIP] Serialization: rewrote the read/write interface to be more consistent and use nullptr when no key is supplied

[WIP] Json Serialization: Adding support for new types, and fixing bugs with reflection and deserialization

[FEAT] Plugin Reloading while debugging: Implemented workaround for MSVC debuger that stupidly never unlocks used .pbd files

[FIX] Input: made Input engine owned variable instead of static, and exposed it to the plugin interface

[STRUCTURE] Back to MSVC: Couldn't get libc++ to work with clang-cl, fixed natvis files for some ecs types

[FEAT+FIX] Plugins: Implemented fluid NodeBuilder in the plugin interface, fixed bug in plugin-shared global state by injecting pointers into the loadPlugin() interface

[FIX] Bug in TypeName.h: Types defined in a DLL was not corectly null-terminated. Added an explicit '\0' to the end of the string

[FEAT] Filesystem/Serialization: Implemented Filesystem+FileHandle interfaces, IStreamStorage interface, and IWriter/IReader that formats data into IStreamStorages, which in turn can be backed by an IFileHandle
