WARNING: THIS PATCH CHANGES CONFIG_BLOCK_VERSION
backup your settings to a config file before applying
if you don't want to lose them.

Adds "Numeric" as a sorting option for files. This
option sorts by leading numbers in preference to normal
alphabetic sort, failing over to alpha sort if no
numbers are present, or the numeric values are equal.

This option would not be necessary if everyone ripped
their albums with '05'...'10' style track names, but
some people prever '5'...'10' which makes alpha sort
look and sound bad.

Had to add another bit to the sort_file option for
this. Perhaps this would be a good time to add alpha
desc as an option as well as any other two options that
have been waiting for a good reason to bump the config
block version.
