Implemented basic ErrorHandler

* InputXSLT::ErrorHandler is derived from xercesc::ErrorHandler and enables contextual printing of transformation errors
** currently this means that the error messages passed to std::cerr contain the full path of the offending transformation
* added input trimming to the external transform function
** calls to this function from inside a transformation may contain unnecessary whitespace characters which disrupt further processing
