[system settings/cellular] Bad UX when no SIM cards are present

[Jonas G. Drange]

We currently have no spec for the cellular page[1] when no SIM(s) are inserted and when flight mode is ON. I do not think it is solved by [2] – cellular hardware *is* present (the modem/slot/antenna).

The current UI (remove the SIM and reboot to see for yourself) is a single-sim-looking, insensitive UI. The unfortunate design of the disabled ItemSelector makes this very confusing.

I suggest insensitive text strings, e.g. "No SIM cards detected" or "Flight mode is enabled".

<https://wiki.ubuntu.com/Networking#cellular-mobile>: "If no SIM is detected, the screen should contain only the placeholder text “No SIM detected”, with caption “Insert a SIM, then restart the phone.”."

Added flight mode and made the description a bit clearer.

  [ Ken VanDine ]
  * Fix logic error in check for Paired to know if we should add
    ellipsis.

  [ jonas-drange ]
  * [cellular] better ux for no sims (LP: #1377182)

  [ Iain Lane ]
  * Reintroduce the functionality dropped in the Qt 5.4 transition -
    expose the functions we need from QStorageInfo to QML, and copy over
    a heuristic function to tell if a drive is "internal" or not.
  * Make the developerMode property not CONSTANT - this was ignored as
    it's writable.
