Merge lp:~ennp/lightdm-gtk-greeter/lightdm-gtk-greeter-username-stripping into lp:~lightdm-gtk-greeter-team/lightdm-gtk-greeter/trunk

[Heinz Deinhart]

Adds boolean config option username-strip-whitespace in greeter section. If set username will be stripped of whitespace.

Main reason: Quite some users tend to click away screensavers with the spacebar and then login fails because they do not notice the space in front of the user name.
