Find elements with an id, class or name derived By selector where possible

Originally created by SergeyA.

Expressions like $("#myid").value("test") are about two times slower than their Selenium analog
new Select(driver.findElement(By.id("test"))).selectByValue("N")

I believe it is because all selectors are translated to By.cssSelector in NonEmptyNavigator.find without any optimizations by selector type.

I'm not sure that we should be getting into parsing css selectors as this is complex and best left to driver implementations. Given that, if you use a css selector ($("#myid")) a By.cssSelector() search will be performed.

The implementation has been changed to use an appropriate By selector when you use attributes for your search though - e.g. $(id: "myId"), $(name: "user"), $(class: "myClass") will not not perform a By.cssSelector() search anymore.
