Adding PubSub support for any PubSub service

[Olli]

I add some minor changes with this patch so that any PubSub? service which supports xep-0060 can be used in a rudimentary way. PubSub?.org doesn't work anymore and it was not xep-0060 conform. (take a look at the appended patch) Now you are able to get ATOM notifications and subscribe/unsubscribe on a node while using a pubsub service with a flat hirarchy ( pubsub.ik.nu ). Please check my changes for correctness.

Iam no python guy so i have no idea how to add creating/destroying/configuring a pubsub node, browse a pubsub hirarchy, add functionality to discover the features of a pubsub node and so on. Iam very glad to see this cool stuff in the next releases of gajim :)

Hm it looks that this server shows a strange behavior. On my amessage.de account browsing this server (ik.nu) is no problem. With my other account disco won't work as expected. You can also try it on any other pubsub service with flat hierarchy.

(In [c06525d5a3b15a569487d7eff5209e4a23ca544a]) improve pubsub support. fixes #3103

I tried to register something on pubsub.ik.nu, but nothing happened. After closing the window I got the following TB:

(In [7bf7eca099e0c815823578e2c953d8d6d042e6f0]) fix TB when we close pubsub window before we get the answer from the server. see #3103

[asterix]

it's because you closed the window before you got the answer from the server. I fixed that in [7bf7eca099e0c815823578e2c953d8d6d042e6f0] But that's true that there is a problem with this pubsub server. registration are not kept. It works better with the one on gajim.org for example.
