[Indicators] replace the text "Empty!" with something more useful

[Bill Filler]

when clearing the menu on this indicator (and others), the text "Empty!" is displayed. Can we please remove that and put something more useful there. It looks bad. Need advise from design..

--------UX comment---------

We are currently working on some designs for empty states that can be used to form the first impression made on a user or offer useful information. The language used in these states must be consistent with the brand's voice and tone across core apps and platform.

The indicator you are talking about is the notification center.

If the menu is empty show the following message: No notifications.

For RTM we've removed completely the text.

Status changed to 'Confirmed' because the bug affects multiple users.

Relevant code seems to be in unity8, file: qml/Panel/Indicators/DefaultIndicatorPage.qml

@Daniela, the transfer indicator has a similar issue

note that the current label is not translatable, if you change it please make possible to translate as well

Indicator messages should use something contextual such as "No current messages". Providing the more specific context will make this much more obvious what this indicator is used for, especially to the first time user.

@Charles: curious why you're marking this bug as invalid for indicator-transfer?

I think we're confusing three issues here.

First, the Transfers menu should show something more appropriate, like "No active transfers" or something, when there are none. That requires design work.

Second, the Notifications list should show something more appropriate, like "None" or something, when there are none. That requires separate design work.

Third, some code in the indicator system itself is inserting the word "Empty!" into empty indicator menus and should not. For example, right now I'm getting "Empty!" in, of all places, the Network menu (bug 1368675). That should never happen ... but when it *does* happen, for whatever reason, it should be something more elegant, like a silhouetted error icon, or even nothing at all.

Indeed, unity8 is putting that in while the menu has not been loaded yet:

Verified fixed in Ubuntu 15.04 r196. Paty, the "Empty!" text is gone from the code; see my 2014-09-12 comment for why more specific empty-state text belongs in other bug reports.
