Go to definition does not work for imports

[jvican]

When you go to the definition of a selector in an import statement, the IDE does not bring me to the definition of that symbol. I presume that is because the selectors are usually names or strings (at least this is the case in Scalac) and its support need to be special cased.

However, what I find surprising is that go to definition doesn't work for the prefix of the selector either (which is, I believe, a symbol). This seems to confirm that imports are not handled by the IDE, at all. I've tried all the imports in the TreePickler file with no luck.

I think handling them would be very beneficial 👍. I believe this is an IDE bug, so I'm labeling it as such.
