Add select-previous command

[KylePDavis]

Seems like there ought to be a find-and-replace:select-previous to go along with the current find-and-replace:select-next command.
I am trying to mimic some behavior from Ace and I'm unable to without this.

This would be especially useful if you want to duplicate a line in which you want to change to identical strings.

Starting with

["foo", "bar", "foo"]
  ^^^

select-next

["foo", "bar", "foo"]
  ^^^           ^^^

Type and replace

["baz", "bar", "baz"]
  ^^^           ^^^

Reset multi selection

["baz", "bar", "baz"]
                ^

Now if you want to duplicate that line again (changing the words at the same position), moving back to the first occurence is cumbersome. select-previous would make this a lot quicker.

Thinking of this use case specifically, it would be even better if resetting the multi selection returned to the first occurrence. But I guess that warrants another issue.

I am also attempting to copy ace shortcuts, and the feature is still not here. Do you still have the shortcut file of what you did get to work from back then? It could save me some time
