Repl completion should show options rather than cycling.

[rosejn]

Currently completion in the repl seems to just choose the first available completion option and put that, and then each time you hit it cycles to the next option. This isn't especially helpful. It would be far more useful if it worked like tab completion in bash, especially for exploring new APIs. When you complete and there are multiple possibilities, they should get printed to the repl window so you can see the options.

this would be nice but a bigger hassle than it might be worth for now. You can see here https://github.com/ghostandthemachine/rsyntaxtextarea/blob/master/RSyntaxTextArea/trunk/src/org/fife/ui/rtextarea/RTextAreaEditorKit.java#L1039 how the DumbCompletion is implemented. In the near future it would be worth ironing out a clojure api for creating new swing Actions like this. To do what you are talking about would require a new DumbCompletion implementation.
