Dashboard API hooks

File attachment died.

Here is a proof-of-concept patch for hook_dashboard() that does not seem to break anything.

Yes. Simpler == better.

I think we should dynamically alter the permission, though, and possibly the loader function.

+      $info['path'] .'/%dashboard_' . $type => array(
+        'title callback' => 'dashboard_page_title',
+        'page callback' => 'dashboard_page',
+        'page arguments' => array(1),
+        'access arguments' => array('access '. $type .' dashboard'),
+        'type' => MENU_CALLBACK,
+        'file' => 'dashboard.page.inc',
+      ),
...

+function dashboard_dashboard() {
+  return array(
+    'user' => array(
+      'path' => 'dashboard',
+    ),
+  );
 }

The idea of the original patch was to provide sensible defaults for these, and not force module's to implement hook_menu_alter().

Will mess around some more this week.

OK, I think this patch incorporates those notes.

I took one liberty. The 'widgets' callback, I renamed to 'gadgets' for consistency -- but it can be changed back.

However, I did insert a loader function into that path as well, since we will need to load the current dashboard to see what widgets a user already has, since there is no point in displaying 'additional gadgets' that are already in a collection.
