Björn Stenberg c9d98ca927 Added delayed write for settings. Doesn't write until someone else accesses the disk.

Config memory is reset to 0xff and initialized with 'factory defaults' if
a valid header & checksum is not found. Config version number is only
increased when information is _relocated_ or space is _reused_ so that old
versions can read and modify configuration changed by new versions. New
versions should check for the value of '0xff' in each config memory
location used, and reset the setting in question with a factory default if
needed. Memory locations not used by a given version should not be
modified unless the header & checksum test fails.
