Add UI message when queued for wifi due to size.

As it stands, when a download is paused because it's too big to
proceed over mobile, and must proceed over wifi, it looks like any
other paused download, with no indication of why it's paused.  That
may be passable for most other reasons for pausing a download, but it
seems too confusing for this case.  So this change adds a simple
string message that replaces the progress bar when a download is
paused for this reason (the icon also changes to a warning).

The implementation isn't beautiful and could use some improvement, but
I think it's acceptable and necessary.  The exact UI design and
wording are certainly open to change.
