Clean up use of options in JS

[IwanVosloo]

We sometimes have put all the attributes of a JS widget (aka jqueryui widget) on its this.options. I find this confusing and cannot think of a good reason for doing this.

We have moved such attributes in reahl.hashchange.js that did not belong with options to be on this.

What needs to be done still, is to go through all such javascript Widgets and check if any others are still doing this....and fix.
