Reverts the ASCII keymap to proper position of 'O' and 'o' keys, and create a
new keymap for rev 1.2 and earlier of the key matrix with swapped 'O' and '0'
keys.
Keymaps/asdf_keymaps.h: swap '0' and 'O' codes to compensate for physically swapped '0' and 'O' in early prototypes
asdf_ascii.h: fix wrong code for comma (44, 0x2C; was defined as 0x44).
- added asdf_actions.c, asdf_actions.h to place misc. key actions
- asdf.c: asdf_activate_action(): added actions for screen clear and reset
- asdf_config.h, Arch/asdf_arch_atmega328p.c: added defs to specify polarity of data,
strobe, SCREEN_CLEAR and reset outputs.
- Arch/asdf_arch_atmega328p.h: fixed pin definitions for RESET and SCREEN_CLEAR
- Add OSI-compatible mounting holes.
- Adjust keyboard and aligner holes to make room for the OSI mounting holes
- Change "Universal Keyboard" to "Unified Keyboard" in the design files.
