Node Add or Edit

This small modules adds an extra checkbox to node type bundles. When the checkbox is active the module will check if the (current) user has already saved one (or possibly) more nodes of that type and if so, will redirect the user to edit the (last) node for that type instead of adding a new one.
This behaviour is different from the node_limit module for it does not try to remove the links to node/add and therefore simplifies the navigation to edit existing nodes or not.
