Keymaps for several of my boards (#1641)

Keymaps for several of my boards (#1641)

* copied mjt keymaps from archive

* All mjt boards now compile

* fixed jd45-mjt breathing

* Updates to fix SpaceFN but not tested yet.

* Still missing either spacebar or an adjacent keypress.

* Debugging rigged up for use with hid_listen.

* Reverted the default keymap to use tap_layer_key rather than custom.  Moved custom approach to keymap_debug.c

* Fixed the lower-left side of the keymap, which needed more spacers due to the matrix being directly put into the array rather than using the keymap function.

* Cleaned up JD45 keymap that uses tapkey.

* Redid minivan keymap with numsym rather than raise/lower.
Untested.

* Created my MJT keymap for HHKB
Enabled dynamic macros and moved
somoe of the shortcuts around.

* Minor keymap fixes to make them compile without errors.

* Added home/end to right arrow cluster on DYN layer.

* Added more keys to fn and dyn layers.

* It wasn't using my custom layer last time somehow...?  Now it will.

* Compiled and installed at end of day on 8/23

* Moved macros to FKEY layer because Adjust was too hard to get into and out of without some sort of feedback.

* Fixed volume controls... were reversed and disabled.

* Added F13-F15 back to fkeys layer in Minivan

* Created new Planck Keymap that uses the NumSym and FKeys layer approach like the Minivan.

* Removed DYN layer.

* Fixed diagram in planck numsym.

* Cleanup for pull request.

* Roadkit flip phone warning.

* Replaced PLAY_NOTES_ARRAY to PLAY_SONG

* reset the submodules

* checked out specific commits for submodules

* Removed debugging from JD45 shared config.h

* Moved custom rules.mk to apropriate keymap

Reset the shared rules.mk file.
