Investigate whether we can make msgfmt errors non fatal
[PO] po/sl/menus/colors/components.po
../po/sl/menus/colors/components.po:1095: 'msgid' and 'msgstr' entries do not both end with '\n'
/usr/bin/msgfmt: found 1 fatal error
Although incorrect, I would not consider this translation problem a fatal error (and the similar one I previously fixed in the Swedish translation). At the moment it stops the whole build including building other languages when it encounters this error.
It's good to be notified when there are errors, but it should not stop when we can still make a manual.
Maybe do not error out on msgfmt errors at all, or else see if there are other command line options.
