Add find references variant that works more like find in files

[pitkali]

I commonly search through different references to a symbol when, for example, changing the way it should be used.

It would be much more convenient to do, if it was possible to get a buffer working like find in files: listing all occurrences, and allowing you to:

• Click some occurrence to visit its file and line. Inspect/code/whatever.
• Go back to the references list, and without searching again click next occurrence.

I could even use the same for Go to symbol, but that would probably be less useful in general case.
