Add installationIDs to crash reports, so the amount of affected users of a crash can be determined

Uses iOS 6 ASIdentifierManager class or identifierForVendor if the class is not available. Fallback on iOS 5 is to use app path UUID which is generated by iOS when installing the app

Call delegate also if a crash was detected but could not be read

If PLCrashReporter wrote a crash report, that could not be read, no delegate was fired. That could make the app stay in the start up maintenance screen, if it handles crashes on startup.
Though there was no report this ever happened, there is the theoretical chance this could.
Add anonID to crash reports

CrashReporter Key is actually an anonymous ID for each device/installation where the crash occurred
Move calculation of time interval between startup and crash further up in the code

This allows the delegate, e.g. applicationLog, to know about the interval and e.g. include it in the log file

Clean this up!

Thanks @tewha :)
Oh documentation

*doh*
Make sure crash reports incident identifier and key don't have special [] chars and some value

The previously shows [] as part of [TODO], since PLCrashReporter didn't fill them out. Having the incident identifier showing a [ or ] char made it impossible to drag it into the Organizer to get it symbolicated in there
Update documentation on how to add Lumberjack log data
Bump version to 2.5.5 build 10

Also update podspec and changelog
