Upgrade to Strophe.js v1.1.1

Upgrading to Strophe.js v1.1.1 brings us WebSockets and
several bugs have been fixed.
However, one thing has not yet been merged in, see src/core.js#L358.
We should test if this sync mode is still needed anyway. If yes, we
should fix this again in strophe.js and maybe create another pull
request.

TODO documentation:
  - Websockets
Upgrade to jQuery >= 1.9

Removes the two remaining $.browser checks.
ESC stopping all events has been fixed in
[Firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=614304).

About the IE check I don't really know why we had it in the first place.
Do you remember @pstadler?
If we still need it, we might need to check it in another way.
