Setup a mechansim for using selenium populators outside testing contexts.

An extended version of the library functions in #10783 - to allow interacting with workflows, etc.. creating using the API from Selenium. Should make my test prototyping environment in #10784 a bit closer to test case enviornments and allow more rapid development of test cases.
