Checksum 905B. Add 'O' command to write a byte to an I/O location. Address first (00-FF), then the byte to send. Could do with testing on the digital I/O card.

Checksum FF1C. Fix RAM test so that uninstalled RAM is not detected as if present in the ascending memory-fill test. Also improve 'F' command to accept a byte to fill with, and to fill all potential RAM from 2000h to ffffh. Old LDIR-based RAM fill is now 'Z', but still won't work if RAM is only partially installed (i.e. if less than 32k present).

Change '.gitignore' to allow Github to see the HEX file. This is useful for users who want to simply burn an EPROM and run the code without needing to install the RC2014 SDK. Update README to match.
