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
