Add support for parameters

[brogreenmoon]

This was implemented previously and needs to be incorporated in the IDE.

For example, I want to be able to define generic page elements for pages like the following:

With a "Filter" page element defined that has a string parameter, allowing a test case to 'Click Filter "Chocolate Bars"'.

We need to be able to support multiple parameters too, maybe a max of five, or ten?

Notes after discussion: Test routine is dynamic data set. However, this one requires dynamic locator Need mockup and technical design before coding, this is big function
