Supporting File upload via Selenium 1 and 2

To get the idea of the new feature, have a look at the classes 
- org.aludratest.service.gui.component.FileField and 
- org.aludratest.service.gui.component.base.AbstractFileFieldTest.
InputStreams should be closed from the method where they are opened. Otherwise, method's name MUST make clear that it closes the stream parameter, e.g. "saveStreamContentAndClose". I personally would prefer first solution.
