Several fixes 

* Fixed various focus issues with find and replace
  * Focusing the find and replace panels will now focus the find editor
  * Clicking buttons no longer steals focus 
* Fixes specificity issues in the find-and-replace keymap (focus-next-pane works again!)
* `cmd-enter` now just runs a search unless in the replace field where it will replace-all
* Added the ability to copy items from the find-in-project results panel.
