#44 showing "meter" instead of "meters" in italian

[Xet]

there's a problem visualizing visibility in italian:
unit of measurement is "metro" (meter) instead of
"metri" (meters)

i solved with replacing line #599 of
$rootDir/output/pw_output.php from

$me_unit = $this->strings['meter'];

to
$me_unit = $this->strings['meters'];

but i'm not sure this is correct for all languages.
Regards.
