Made saving the display name work the same way as the email address. Fixed a few comparison operators. Increased the fadeOut time for the success and error messages.

doesn't work anymore, because now the datetime is saved as string (ref #2975)

Very hacky

Modified how the #lostpassword or #email fields save email addresses on the Personal settings page. It now saves one second after the last keyup event, instead of after a blur event.

When removing a group response.data.action becomes 'remove', thus the if
shows an empty notification.

Two parameters for OC.dialogs.alert, otherwise one will be "undefined".

Also fixed missing translation.

Fixes #2647
