v1.09

v1.09

This release matches the upstream release v1.09, with the additions I've made along the way.

Upstream changes:

• If uart.txt contains AUTO x will inject the character x into the input buffer on-boot.
  • So AUTO c will load CP/M, AUTO t will load Tinybasic, etc.
  • z80playground#50
• License (GPL-3) added to upstream repository, my changes will be the same.
  • z80playground#53
• Bugfix for GORILLA.BAS.
  • z80playground#49
• Fixes for the PIP command.
  • z80playground#48
• Removal of symbol files.
  • z80playground#54

My changes remain as documented in the README, mostly the addition of documentation and rejigging of the disk-contents.
