Search hierarchically for imported object files
Previously an imported object file:
implementation module test.test import code from "obj.o"
Would only search in the roots of the project paths. Now it will als search in the test/ folder in the root.
This is achieved by remembering in which module the import was done and using this to search hierarchically for the object file. It is backwards compatible, it will only search hierarchically if it failed to find the object file the old fashioned way.
Things I need to do before merging:
- Test on windows
