Support inline output replace on REPL commands

[wilkerlucio]

Add an option on the REPL command to replace the current selection with the result output.

This feature would give us the ability to run custom commands that use the selection to do inline transformations. Currently I have one case: I have a command that sorts the selection, I use that so sort my imports. The currently workflow is to select the items, run the command, copy the output from the REPL, and then paste back. Having the inline result option would speed up this flow and allow other custom flows like this to be created.
