Using ksort now, instead of prefilling the commonlanguages array.

revert changes to fbbc76f2 because master is very unstable right now

Also add russian and arabic to the common languages.

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.
