Added 2 options to the "Capture Control" (Alt-C) menu:

- Binary
- Binary with SAUCE

These options save the current screen to a "BinaryText" (*.bin) file,
optionally with a SAUCE record. If you want to screen-capture in SyncTERM,
this is how you do it. It'd be cool if the PrintScrn key did this without
any kind of popup/prompt, but that's a feature for another time
(if at all).
