Fixing Makefiles for new nodes module, part 1:

- removed all UI .h include stuff! (Not allowed outside of src/)
- Makefile had typo error, compilation failed

Now it survives make, but it does not enter the two the subdirectories for
shader and compo nodes. So a linking gives unrecovered stuff in the end.
How does that work? I need help!
