Tooltip for entities

[Masterz69]

Right now see, f.e. in Device screen in Settings, in tooltip just the same entity friendly name.
Woulde be nice to define tooptip text for each & every entity to show additional info for user.

Just for example - hovering over entity tooltip appears with same name, which is actually useless IMHO

Would be nice to define some comment/details of entity to be shown as tooltip in browser.
