Upload files over the console (YMODEM) - #123
Merged

Conversation
scripts/ymodem_send.py sends files to the device over its UART console: it types dmell's `ymodem recv -d DEST`, waits for the receiver and sends a YMODEM batch (1024 / 128-byte blocks, CRC-16) - directories with everything in them, names kept under DEST. Only the standard library. The upload-files target sends DMBOOT_UPLOAD_SOURCES (build/sdcard by default) to the running device, install-all flashes first and waits for it to start.
