Fixing default ErgoDox layout and adding FlashMode button

Browse source 
- Adds proper flashMode support for all keyboards and microcontrollers (usb and serial)
- flashModeEnabled must be set to 1 otherwise it will only show an error
  * This is on purpose (somewhat dangerous feature as it allows remote flashing)
- Capability cleanup
