* rename LAYOUT to LAYOUT_65_ansi_blocker; enable Community Layout support
* refactor default keymaps
Updates grid alignment of keycodes, and adds a Function layer to the default keymap.
* refactor LAYOUT_iso into LAYOUT_65_iso_blocker_split_bs
Adds missing KC_NUBS position, and moves Enter keycode to home row (consistent with QMK Community Layout).
* remove LAYOUT_split_left_shift
With the changes to LAYOUT_65_iso_blocker_split_bs, LAYOUT_split_left_shift maps all the same positions, but in a different sequence, making it redundant.
* refactor LAYOUT_7u_space to LAYOUT_65_iso_blocker_tsangan_split_bs
Moves Enter keycode to home row.
* remove LAYOUT_split_space_1
LAYOUT_split_space_1 differs from LAYOUT_split_space_2 only in the sizes of the split spacebars, and I like the layout rendering of LAYOUT_split_space_2 better. :)
* refactor LAYOUT_split_space_2 into LAYOUT_all
ANSI Enter, split Backspace, split Left Shift, and Split Spacebar.
* add LAYOUT_65_ansi_blocker_split_bs
* add LAYOUT_65_ansi_blocker_tsangan_split_bs
* add LAYOUT_65_iso_blocker
* ginkgo65.h: touch-up block diagrams
* info.json: use maintainer's GitHub username
* bugfix layout macros
Position k1D wasn't being assigned on the ISO layouts or LAYOUT_all.
* rules.mk: update Community Layout support
