Finally calling JSONLab complete.

Today’s work was mostly polishing:
-Fixed another UI state bug where actions like Format, Validate, and Minify could still be triggered while in Tree view.
-Disabled actions that don’t apply to the current view.
-Cleaned up a few more UI inconsistencies.

At some point you have to stop polishing and ship. I hope this is the last round of tweaks for JSONLab and that there won’t be any more polishing or updates needed. Time to move on to the next project.
