[Pligg CMS] Add BB bar + 2 small changes

READ DESCRIPTION BEFORE BIDDING - I want this specific BBcode bar ([login to view URL]) installed on my Pligg CMD when submitting a story. At this moment you can only write text. - at this moment you need to fill in a story srouce link BEFORE writing a story. I'd like this: [login to view URL] to be placed here [login to view URL] And then just skip the whole step one. - At this moment the system grabs the thumbnail from the source URL. I'd like it so that people can choose a specific featured Image that will be shown as a thumbnail in the story list 'but it will not be shown when opening the story)
