Printing cause of exception when present
removed check for php 5.3 when printing the cause of events
Adding test for TextUi when tests use an exception stack
Fixed the way PHPUnit_Util_Configuration parses listener constructor arguments

Previously, getListenerConfiguration assumed the <arguments> element
would always be the second element (index 1) because nicely formatted
XML has a DOMText node containing a newline and some space before the
arguments node. Computer-generated XML places the arguments element
immediately after the listener element, so the node would be at index 0,
causing the arguments node to not be found. Instead, it now searches
the entire listener node for argument nodes.
