I just update lib-common.

Now all of my stories and all the items in media gallery now get a distinct
description and keyword meta tag.

The change for media gallery was done only today so the result needs to be seen.
But the changes in the story section have yielded great results.

where earlier my pages were not comming in any searches have started to appear now.

I would like that someone from the GL team can take this code add it in next GL release.
and if they have time then improve it.

Text Formatted Code
