* Add vlukash CrKbd keymap to support trackpad adapter. The trackpad adapter uses Elite-C board that has five extra pins. Also SPI pins are taken for trackpad, keymap config updates column data pins for matrix scan. * Update vlukash keymap * Enable pointing devide, configure mouse BTN1 * Set TAPPING_TERM to 300 * Add support for the BlackBerry 8520 trackpad * Add vlukash keymap for master-right no-trackpad version * Remap backspace * Set EXTRAKEY_ENABLE = yes * Update thumb keys mappings * Set bootloader to atmel-dfu * Sync keymap * Add scrolling support * Make debug LEDS conditional * Add support for both flex and no-flex PCBs * Add readme and rename root folders * Update readme file with blog link * Fix readme file formatting * Remove ADJUST keycode, code cleanup. * Add Win key to the keymap.
