* convert codebase to #pragma once
* fix file includes
- quantum.h is included at keyboard level, redundant at revision level
- keyboard-level path is accessible at revision level, remove relative pathing
* duplicate common layout macros from rev1 to rev2
Add the layout macros supported by both rev1 and rev2 to rev2.h directly, which exposes these layouts to QMK Configurator.
* enable community layout support (75_ansi, 75_iso)
* add LAYOUT_75_iso layout data
It needs its own tree because its keys are in a different order from LAYOUT_iso_1u even though the physical layout is the same.
* minimize rules.mk files (use QMK defaults)
* use atmel-dfu bootloader rule
* fix typo on rev1 info.json
