wrapper function to create arbitrary activities (e.g. for plugins and apps) with a minimal amount of fuss, though the amount of fuss could increase significantly depending on the nature of the activity. For a simple wall post, just set the $arr['body'] to the desired text and we'll do the rest. If the activity requires special verbs, objects or targets, these will all need to be constructed.
