Massive localisation overhaul to CrashReporter

* Localisation keys are now actual keys independent of the English translation.
* Fixed some missing keys in the localisation files
* Implemented all missing strings in code. (`COPY`, `EDIT`, `VIEW_IN_CYDIA`, etc.)
* Added an `INSTALL` key (binds to `Install %@`) for the Syslog Flipswitch/Toggle alert view.
* Translated some missing strings in the Chinese translation (Japanese translation still incomplete and not committed yet)
* `nil`'d out the comment argument for all instances of `NSLocalizedString` for consistency
* `nil`'d out the `value:` argument for all instances of `localizedStringForKey` for consistency
