External interface shows as up fake

On the network topology router-mouse-over-balloon, the list of
interfaces contains one labeled "fake<some_id>" which is a placeholder
for the external interface.

This interface should be labeled with a much less confusing tag.
"extern" or "gateway" seems much better.

Change 'update default quotas' success and failure messages

Success and failure messages include formatting that adds name,
which makes for awkward phrasing when displayed to the user.
Removed formatting to clarify message text for both success and
failure messages.

Make object upload success message translatable.

Since the corresponding request is not ajax, we should
use "force_unicode" to translate the message.
