* **v1.0** Buggy initial release
* **v1.1** Small changes to system settings and EEPROM storage.
* **v1.2** Added wild card to listing and remove commands. Added read file command.
* **v1.3** Added auto buffer record if unit sits idle for more than 5 seconds.
* **v1.4** Increase buffer size to 900 bytes. Pinning down URU errors.
* **v1.5** Lowered power consumption to ~2mA avg. Added 4800 and 19200 baud rates.
* **v1.51** Added configurable escape character, and escape character amount.
* **v1.6** Added ability to configure via config.txt file.
* **v2.0** Massive overhaul. Ported to sdfatlib. Now supports FAT16/FAT32/SD/SDHC.
* **v2.1** Power save not working. Fixed issue 35. Dropping characters at 57600bps.
* **v2.11** Tested with 16GB microSD. Fixed issues 30 & 34. Re-enable power save.
* **v2.2** Modified append_file() to use a single buffer. Increased HardwareSerial.cpp buffer to 512 bytes.
* **v2.21** ringp fork brought in. rm dir, cd .., and wildcards now work!
* **v2.3** Migrated to v10.10.10 of sdfatlib. Moved to inline RX interrupt and buffer.
* **v2.4** Merged ringp updates. Commands cd, rm, ls work again!
* **v2.41** Power loss bug fixed. Adding support for 38400bps for testing with SparkFum 9DOF IMU logging.
* **v2.5** Added software reset command. Modified the read command to print extended ASCII characters.
* **v2.51** Changed command prompt control to ignore \n for easier control from microcontroller.
