I don't really remember why I added the URL in the first place anyway ;p.

This change breaks HTTP calls on Tolino(only tested on my tolino vision 4 hd) devices, because Device:info() returns a multi line string:

/koreader/device/info ()
  function Device:info()

Nb args: 0

Success
Nb returned values: 1
  1: string: ntx_6sl

Betriebssystem: Android KitKat, api 19 auf arm
Build-Variante: rocks

E-Ink Display unterstützt.
Plattform: freescale


Returned values as JSON:
["ntx_6sl\n\nBetriebssystem: Android KitKat, api 19 auf arm\nBuild-Variante: rocks\n\nE-Ink Display unterstützt.\nPlattform: freescale\n"]

This results in invalid headers being send within HTTP requests.

Thanks, indeed that goes far beyond the Device.model I thought it was for (just with the freedom for some custom logic to get something more than just a generic "Android").

I just installed the latest nightly and I can confirm the fix works. Thanks!
