x-axis is reversed

Hi mate, SEO watcher is a great little module, it's been a big help to me :)

Anyway the x-axis labels appear to be the other way around to the graph (the graphic is left to right from youngest to oldest, and the axis is left to right from oldest to youngest). I made a little fix to this by simply reversing the $ranks variable in seowatcher.module, and modified lines 196-198 from this:

$ranks = seowatcher_load_past_rankings($provider, $keyword);
$legend .= seowatcher_get_provider_name($provider) . '|';

to this:

$ranks = seowatcher_load_past_rankings($provider, $keyword);
$legend .= seowatcher_get_provider_name($provider) . '|';
$ranks = array_reverse($ranks);
