Provide a generic loader for menu items

Just what the doctor ordered.

Wouldn't you need to use 'load arguments' => array(1, 'myentity')?

ad #3: I think the documented load arguments are fine.

@patch: Makes sense to me. However, we should also update the 'admin ui' provided with the entity API to make use of it. Thus, changing the default for 'menu wildcard' + updating the docs that ENTITY_TYPE_load() is not required any more should do it. (see entity.api.php).

+    if ($entities) {
+      return reset($entities);
+    }

I don't think we need this check, as reset() is fine with empty arrays and just returns FALSE.
Also, why do we need to catch exceptions here? Usually we don't do so?

Here you go.

entity_object_load() could also be a wrapper around entity_load_single(), once #1027908: entity_load() should return entities keyed by ID, not name lands.

thanks, committed.

Hrm, the load arguments still look wrong. According to the example, 'myentity' is going to be passed in as the entity_id and there is no value for the entity_type parameter.
