Merge lp:~nataliabidart/ubuntuone-control-panel/use-webclient into lp:ubuntuone-control-panel

[Natalia Bidart]

 - Replaced custom webclient with the one from ubuntu-sso-client
   (LP: #926311).
- Removed the dependency on qt4reactor for Linux implementation.

[Roberto Alsina (ralsina)]

Looks good to me....

review: Approve

[Natalia Bidart (nataliabidart)]

The controlpanel, in order to run on windows, will need:

https://code.launchpad.net/~nataliabidart/ubuntu-sso-client/delay-reactor-import/+merge/91712

[Alejandro J. Cura (alecu)]

Code looks nice, all tests pass, tested IRL on linux.

review: Approve

[Ubuntu One Auto Pilot (otto-pilot)]

The attempt to merge lp:~nataliabidart/ubuntuone-control-panel/use-webclient into lp:ubuntuone-control-panel failed. Below is the output from the failed tests.
