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.
