Keyboard: Add Handwired 108 Key with Trackpoint (#4448)

* Include both base keyboards

* Merge the keymap

* Merge the configs

* Add wiring diagram for clarity of documentation

* Merge rules

* Merge keyboard sources

* Change names to compile

* Update documentation to suit

* Add qwerty layout to 108keyTrackpoint

* Separate the dvorak standard layout from a media focused one

* Update documentation to reflect new keymaps

* [style] Add empty lines at ends of files

* [style] Meet current QMK style guide

* Bring READEME closer to the QMK template

* [style] Change all "108keyTrackpoint" to "108key_trackpoint"

* [style] Use "LAYOUT" instead of "KEYMAP"

QMK terminology has changed

* Add two spaces after maintainer in README

This is required to render properly

* Remove redundant line

"PREVENT_STUCK_MODIFIERS" is default on for QMK

* Change include of keymaps to use QMK_KEYBOARD_H

This includes automatically

* Update make rules to match template

* Change from KC_MENU to KC_APP

The button functionality actually wanted is the context menu key

* [style] Change "dvorakMedia" to "dvorak_media"

* Update README to reflect minor changes
