[patch] correct spelling errors

[ansgar]

Hi,

the attached patch corrects some spelling errors that I found while updating the Debian package (lintian, one of Debian's QA tools, finds some common spelling errors in binary programs).
One spelling error remains: "artifical" (instead of "artificial").  I did not correct this one as it was also present in the translations.

Note: The patch is against the sources for 102.2.2.

Regards,
Ansgar
