Inside of Builder.jquery, allow for default options

[twolfson]

Currently, it is clunky to specify default options for a plugin. You always have to wrap it in another plugin, we should provide some help here.

Add another option called defaultOpts or something similar which can either be a function (which is run on the element) or anything else (used as first parameter).

We might even one to upgrade it by making it an array and using .apply all the time. However, that would be best suited as another property for a high/low level API.
