Title editor to get focus and select text title

[ornus]

When node rename starts editor should get focus. It's convinient.

Optionally (this is how developer decides) edited node title should be selected. This is handy when adding a new node. Node will get "New node" title by default, enter edit mode and select text to replace it. I think this behavior is standard (all trees I can remember select title text when you attempt to rename it).

Yeah, that's how it works now.
