Various fixes to CrashReporter

* Fixed "CrashReporter" string in Localisations so that `localizedStringForKey:@"CrashReporter"` actually works.
* Fixed grammar in English localisation (English.lproj).
* Converted Chinese localisations to use UTF-8.
* Fixed some odd encoding errors with the English localisations.
* Added `.gitignore` so Theos build artifacts are properly ignored by Git.
* Fixed unlocalised lines in `SuspectViewController` using `NSLocalizedString`.
