Fixed two bugs regarding the Intel TSX specification: XABORT was not working. XTEST returned the wrong return code.

Enhancements to editor

Add convenience features to the code editor. Currently, I'm thinking only of `undo` and `redo`, but there might be other simple enhancements useful. So, if anyone has suggestions, please post...

Add configuration/options entry to switch between hex and decimal representation of the register values

The code in the `RegisterFrame` already implements this functionality, but an entry in the options dialogue is missing. Also code in `Preferences` needs to be added.
