Replaced sbsettingssyslogd with de.j-gessner.syslogflipswitch, and fixed grammar in the English localisation. Changed Chinese localisations to use UTF-8.

Replaced sbsettingssyslogd with de.j-gessner.syslogflipswitch because SBSettings is currently incompatible with iOS 7.

Also, fixed a minor grammar issue that was bothering me ("Crash reports without syslog ~~is~~ **are** often useless.")

Chinese localisations have been modified to use UTF-8 instead.

I am also working on a Japanese localisation for CrashReporter, but that is not complete yet, and is not in this pull request.
