[Translators] typos?

[Thomas Bellmann]

The latest pot file contains five strings with 
 "[a-zA-Z0-9] :"
(e.g. msgid "Server Name :")
and four more strings which have a leading blank before the colon
(e.g. msgid " : new mail")

At least for the former I am sure they are typos but for the latter I
am not sure. So far I corrected them all in the translation.
It seems as I started translating I didn't question the blanks but
adopted them from the msgid string.


Best Regards
