Fixed memory leak in GiftiFileSaxReader.  The leak occurred if GiftiDataArray::readFromText() threw a GiftiException.  Now, when the GiftiException is caught in GiftiFileSaxReader::processArrayData(), the 'dataArray' is deleted.
Add code in Brain's file reading to catch bad_alloc exception and any exception but it is not catching the exceptions.  Will try on another O/S.
