Subject: altos: Flush the on-board mega log after every sample interval.
X-Git-Tag: altosdroid_v1.2-1~46

altos: Flush the on-board mega log after every sample interval.

SPI flash parts don't need flushing, but the SD card does. Make sure
the SD card contents are sane after every logging interval has passed
by flushing all dirty blocks to the device.
