Picture posts for statusnet, picture posts with twitter are working again - and some "fromglus" stuff

In the last days the posting of pictures to twitter stopped working. I guess that twitter changed something that our current library can't cope with.

For this reason I added a small twitter library that is now used for posting images. If everything looks good I will change all twitter calls to this library.

I used a modified version of this library to enable picture posts to statusnet. (Which didn't work with the old library as well)

Other stuff I added: if a post is fetched from G+ then the system now embeds bigger images. Additionally there was a problem that sometimes the same message was posted above and below an image. This is solved as well.

And finally there was a problem that sometimes a post to twitter wasn't sent because it would be too long. This is some kind of the "shouldn't happen" things, since the system respects the fact the the twitter shortener isn't very good.

I built some stuff to cope with that situation. it isn't perfect but I hope that it will work.
