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.

* Trailing return issue in rules.mk

Gotta make for a smooth pull request :-)

+# Flip Phone layout for Roadkit
+
+BEWARE, THIS DOES NOT WORK YET. 
+
+Uses the numpad with classic cellular phone style letters assigned to the numbers.
+
+# LAYERS
+
+* Numpad - The layer that matches the caps mostly
+* FPH - Base layer for text
+* FPHNOISY - Text layer that outputs every character and then backspaces as they're replaced
+* DYN - dynamic macro layer for recording and playing macros
+
+## FPH
+
+Poke the "2" key twice and it makes "B".
+
+## FPHNOISY
+
+Poke the "2" key twice and it makes "A"+backspace+"B" so you can see it cycle through.
+
+## MACROS
+
+May be able to record macros with the T9 layer because the "KC_*"s are only sent
+at the end.  Trying to do a macro with T9NOISY would probably fill up the buffer
+in just a few characters.

+# Mike's custom keymap for roadkit
+
+Based on the 13 key layout.
+
+## LAYERS
+
+* Numpad - The layer that matches the caps
+* Excel - / * - = and () [] {} macros
+* Navigation - arrow keys and home/end
+* ADJUST - just like planck adjust, lets you set default layer.
+* DYN - dynamic macro layer for recording and playing macros
+
+## MACROS
+
+Sadly, the dynamic macros are probably going worthless because they keys that
+they record have to be pressed on this keyboard. This keyboard doesn't have
+most letters...
+
+## LEADER KEYS
+
+This board would probably be better with the user of leader keys instead of
+complex layers with a raise/lower setup...  Something to look into for later.
