Added tests/current-bugs (#1781)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Added a current-bugs folder in tests for active (ie with issue) bug tests demonstrating the problem.

+// NOTE! This test should *fail*, if preprocessor is working correctly!
+
+// This demonstrates the existance of a bug in Slang preprocessor macro expansion. Could be due to incorrect paste handling
+// or perhaps the rules around parameter expansion.
