Renamed TryFindElement with OptionalElement
Added xmldoc documentation to the IElementFinder interface and cleaned up the variable names
Added a wait to OptionalElement methods for consistency
Added acceptance tests for the Element method
Added an acceptance test to check the OptionalElement method and included a fix for a bug I introduced with an earlier commit
Added the ability to control the implicit wait inside Selenium so that tests with known elements that can't be found can be made to execute faster than 10s!
Tweaked timing on acceptance test project
