Changed "File > Assemble" to "File > Generate Assembly". Also, correctly mark a read-only text field as such.
I managed to work around most of the quirks, but there's still an issue with 65816 code. Also, enabled word wrapping in the AsmGen text boxes.
- Updated the tutorial to track changes to WPF, and to clarify existing content. - Fixed Ctrl+H Ctrl+C, which was getting masked by the Copy command handler. - Fixed initial selection of address in Set Address.
