* [Keyboard] GH60 v1.3 Support
* clean up info.json
Update key sizes and positioning.
* add readme
* add image to readme
* fix up info.json LAYOUT_all
* add LAYOUT_60_ansi
I'm guessing at this based on a photo of the PCB. Chances are high that this isn't fully functional.
* add matrix block comment to v1p3.h
* add default_ansi keymap
* add keymap readme files
* fix LAYOUT_60_ansi macro
* enable 60_ansi Community Layout support
* add layouts for 60_ansi_arrow
Add LAYOUT_60_ansi_arrow and LAYOUT_60_ansi_arrow_split_bs macros. (The user helping me test runs the split Backspace variant.)
* add Tsangan, HHKB, and 64_ansi layout macros
* add factory keymaps and layout info
* update copyright headers
I mean... if someone's gotta "own" this code...
* fix broken factory_* keymaps
