Add personal userspace, update keymaps (#4845)

* Add kbd6x:konstantin keymap * Prevent tap dance from sending LShift as a weak mod in KBD6X * Move config.h and rules.mk definitions into userspace * Add UC_WIN to UNICODE_SELECTED_MODES * Temporarily use Bootmagic until Command is fixed * Move common behavior from keyboards into userspace * Update kbd6x:konstantin keymap and userspace * Make a RCTRL layer in kbd6x:konstantin * Make KC_ESC turn off layers * KC_ESC turns L_FN off only if it was locked on * Add missing record->event.pressed checks * Move numpad toggling logic into function * Disable Bootmagic, enable KEYBOARD_SHARED_EP with Command
