provide better ui feedback to create space

now on creating a space a status message is shown (for users with slow internets)
this status message disappears on completion of the action
input box is cleared on a successful create (note checkbox is retained as a user
might be wanting to create lots of spaces which include the current space so is left
in control)
this required a bit of a rejig of the template used to generate the form.
