Allow multiple embeded actions on a single page to use different stylesheet

[vbrown608]

Currently, both share the settings defined in the ac_embed javascript variable. It would be great to either allow separate settings passed to the embed script or put a distinct body class on the embedded iframe for more targeted styling.

(See https://savecrypto.org/ for an example of two embeds on one page.)

I think this was a bit of an edge case...I'm going to close this and we can reopen if it comes up again.
