Spaces Taxonomy settings form.

A node can only belong to one space, so only provide options for the Space vocabulary that are single valued. This means that:

1) In various hook_form_alters we will need to disable the cardinality selection on term references that are for this specified Spaces vocab. 2) On any term reference field in a node form, do not allow them to change the value of this vocabulary once it has been selected.
