catch hidden OOM errors when data transformation text results passed for display in a text window

There are many cases where Jalview passes a stringbuffer containing some text report to a CutAndPasteTransfer window, usually with the following code:
cap.setText(analysisClass.getResultReport().toString())

At the very least, these cases should always be wrapped with an OOM try/catch handler.
Ideally, result reports should also be passed and processed by reference to minimise overheads even further.
