* handle particles project VC++ compilation errors with MVCS and project property changes - retarget to v142 platformtoolset - remove explicit windows SDK version; use latest by default - remove settings that are otherwise default values in project or are best determined by solution * attempt to handle clang++ issues regarding unsupported c++11 features * reset file changes to particledefs.h * removing PARTICLEDLL_API definition and replacing usage with extern "C" block statements * add g++ compiler option to specify c++11 standard * attempt to resolve forward enum errors by adding std to base cflags * replacing deprecated libstdc++ and removing -lstdc++ flag, updating MacOSX10 sdk version * small refactor to Makefiles, and add libstdc++ back to linux build * remove added type to enum * reset makefile changes that may be causing unexpected linux build failures * refactoring std=c++11 declarations in Makefile to mitgate linux build failing * ensure std is set for hl_cdll make * attempt to define a standard library to resolve vector initialization_list constructor issue * attempt to update MacOS sdk, set minimum os to be 10.7, and include export in travis ci to define deployment target
