Integrate jquery in Mainframe / json as a jquery plugin

[nimix]

For the majority of jquery plugins you need to have jquery in the same frame as the Dom-Elements you want to modify. So it would be cool to have jquery in the main frame to use it for the UI. The problem is that json, which we already have in the main frame, and jquery don't like each other. So the solution is to replace the now used json.js with a jquery plugin which will do the same within jquery. The change will be that you call $.toJSON(obj) instead of obj.toJSONString().
