By updating to this commit, Linux users have to regenerate Makefiles by re-running the configure script. * Added yaml-cpp project as a 3rdparty library * Migrated source files core to C++ * Updated configure scripts * Make Linux installations compile *.cpp files * Made server components' main source file C++ * Also made headers CPP-aware. * Added basic C wrapper for yaml-cpp library * YAML-node path is delimited by periods. * Basic integer types and string are supported. * Strings returned from this wrapper have to be freed with malloc.h::aFree * Arrays (sequence) is supported with iterator wrapper. * Remember to free every wrapper you create! * Add yaml-cpp as dependency of common project * Made the repo not ignore *.yml files Thanks to @aleos89 and @Lemongrass3110.
