GSV sentence not handled correctly when there is only a single satellite present

[njtromp]

The following sentence (which my Nokia LD-3W Bluetooth GPS dongle emitted today) results in a 'not enough tokens' error in the codes/GSV.js module.

$GPGSV,3,3,09,24,06,148,22*4D

According to this information http://www.gpsinformation.org/dale/nmea.htm#GSV there can be up to four satellites present in a GSV sentence. The above sentence only holds information for a single satellite. Which makes sense given the fact that there are 9 satellites and this is the third GSV sentence.
As far as I can tell the check done on line 9 of codes/GSV.js 'if(tokens.length < 13) {' should check for a minimum of 8 tokens. The current check assumes that there are at least two satellites 4 + 2x4 = 12 (plus a mysterious extra token??) tokens while there can be 4 +1x4 = 8 tokens when there is only one satellite.
