iframe selectors, additional methods

[coinzdude]

when targeting iframes, it's not always possible or reliable to match on index, particularly if iframes are generated dynamically. Additional methods to base the selection of the target iframe would be helpful. Possible useful targets for selecting iframes would include

by index (which we have) by ID by url by locators

Generally, these should only match descendants, vs ascendants, however, the recorder would also ideally take this in consideration when generating the commands, to inject prerequisite "back to top" or "up" frame navigation to accommodate.
