- Added clang (i.e. multi-compiler) support to convenience build scripts
- Updated README
- Added Bootloader build scripts for the two main versions currently used
- Added uartOut and usbMuxUart build scripts (these tend to suffer from build rot the most as they're only used in debugging)
- Attempt to get clang support for the Bootloader
* clang is missing compiler extensions, so this may require a large re-write to get working
- 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
