Templates don't distinguish between sub-albums und sub-galleries

[GoogleCodeExporter]

From the template point of view, sub-albums and sub-galleries are the same. If 
you have to know what you are dealing with you have to look at the ID (the key 
of $galleries in an album-template). If it is prefixed with an "a", then you 
have an album.

In the template, you must use code like this:
foreach ($galleries as $key => $gallery) {
  if (substr( $key, 0, 1) == 'a') { 
    $isAlbum = true;
  }
... some template stuff happens here ...
}

It might be easier preset some field in nggCreateAlbum() like 
$galleries[$key]->isAlbum to true/false and then use this in the template. What 
do you think about this?
