Asset renaming popup

[Dgzt]

Is your feature request related to a problem? Please describe.
There is Rename Asset menu item on Assets dock if user clicks onto a asset with right mouse button but this button does nothing currently.

Describe the solution you'd like
It would be nice to show a popup where the user can edit name of texture. Like game object renaming popup.

Additional context

I gave it a try. The user can set a display name that is only used in the ui. I think this is less error prone than changing things on the file system.
