Merge lp:~mandel/ubuntuone-windows-installer/add_ubuntu_sso_service_skeleton into lp:ubuntuone-windows-installer/beta

[Manuel de la Peña]

Provides the initial skeleton of the Ubuntu SSO on windows.

[Rick McBride (rmcbride)]

Only one minor problem and this should be fine.

In several places you have "Ubuntu One" as "UbuntuOne" without the space. This needs to be fixed.

Once that is done I'll approve this.
