Update Bootstrap.php
When calling WebDriver::attachFile(), if the specified file does not
exist, RemoteWebElement::sendKeys() winds up being called anyway and
then WebDriverKeys::encode attempts to do a "foreach" over a null.  

This fails with " [ErrorException] Invalid argument supplied for
foreach()". This errors is confusing to the folks we are trying to train
to do test automation.  

Modfied WebDriver::attachFile() to verify that the file exists and is
readable.  If not, an exception is thrown.
