Subject: Move include directory (#337)

* 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
