Move include directory (#337)v1.11.0-rc1
* Move include directory to shared folder This commit moves the `include` directory from the NorthstarDLL project folder to the solution folder. This allows both the DLL and Launcher project to target it properly. * Fix filters * Update memalloc.h * Fix filters * Update NorthstarLauncher.vcxproj * Remove stuff from other PR * Update NorthstarLauncher.vcxproj * Update NorthstarLauncher.vcxproj * Update NorthstarDLL.vcxproj
