Add another reference for firefox profile config entries
Add inner_window_size sub and init hash key option

The optional hash key can be used to immediately resize your browser
window directly after instantiation of the browser.

The hash key calls out to the similarly named sub routine which opens a
new window, closes the old window, resizes the new one, and switches
handles appropriately.
Rework recorder to allow it to be called from anywhere
