Overview

Multiple minor bug fixes across many subsystems. Adds SDIO (4-bit high speed) SD card support and moves to untouched SdFat upstream library. Speeds of up to 15MB/s with this mode have been shown, well above 1-bit SPI mode (but it does require a new physical adapter with all 4 DAT0...DAT3 pins). ExFAT support is now enabled as well, allowing for very large card access.
