replace Crittercism with Crashlytics, suckily

Crittercism is dropping free support of FOSS apps, so I'm dropping
it. Unfortunatly integration isn't as clean: so far at least I haven't
figured out how to make it possible for others to build the 'd' variant,
which includes Crashlytics, without their having a Fabric API key.
