Changes test for ISO 6709 location format

As discussed with Mika this changes the ISO 6709 detection to use:
	1st non-whitespace character is a digit and
        number of commas is even.

The idea is that, as all the other formats seperate the lat from
long with a single comma, additional even numbers of commas could
ocour in locales where comma is used as a decimal point, but in
total an even number of commas (often 0) would indicate an ISO
format entry.
