update to jquery 1.11.1 ( latest ) removed old versions, fixed $.browser
ref.

* Note in our present versions we are doing min with our php-lib instead
of using the closure compiled version ( this results in a few extra k )
* In later versions of the meWembed loader you can specify
pre-compressed libs, which could improve initial loading performance.
