Search for Northstar.dll in profile directory (#451)v1.17.0-rc2v1.17.0-rc1v1.17.0

Looks for `Northstar.dll` in the specified profile directory using `-profile=<dir>`. If it doesn't exist it defaults to the `Northstar.dll` in the root directory.

This allows for having a separate DLL for each profile.
