Currently when set to wifi only system-image-dbus creates a download
with the "allowOverGSM" property set to false, which then sits in the
queue until the user gets a wifi connection, and appears to report to
system settings that the download has started (despite it actually just
being queued).

To handle cases where the user is on GSM and still wants to download the
image I think we need to modify system-image-dbus to report the status
of the download as being queued while waiting for GSM, this way system
settings could provide some form of "download now" button that causes
system-image-dbus to set the "allowOverGSM" property on the download
back to true and so force the download to start immediately.

This currently causes additional problems due to the network status
sometimes being reported incorrectly as still being GSM when really on
wifi due to bug #1528886, meaning the download isn't started even when
the user really is on wifi. Fixing that will lessen this issue, but it
should still be fixed to account for users on GSM who want to force the
update to start anyway.

Bug description:
  Ubuntu Touch 15.04 (r23) [mako]

  Issue: Phone appears to fail to receive OTA updates. Previously, I jumped 
from (r15) to (r23) due to missing OTA updates. Currently, I see (r24) appears 
to be released on 2015 Oct 16.
  Expected behavior: System Settings > System > Updates (or System Settings > 
About this phone > Check for updates) reveals new image that I can release and 
download.
  Actual behavior: Checking for updates... > Software is up to date

  See the comment regarding similar issues for large app installs.
  It seems if anything interrupts the transfer or if the connection is somewhat 
slow the download performance degenerates then times out.
