Appending old CrashReporter functions  to the main singleton.

(this is a really ugly placeholder and I apologize for it)
adding arc back to AppBladeWebClient
Deleting the PL files sine they were in the wrong place.
Moving all new PLCrash files to their old folder location.
Adding .proto files to source so they can be precompiled.
CrashReporter.h was being referenced in an incorrect location.
PLCrashReporter made a few methods private. We need to publicize them.
For backwards compatibility, some old crashreporter functionality now has to exist in the main class.
adding a build of the compiled protofiles
updating LastUpgradeVerision to Xcode 5
Adding more compatibility methods to AppBlade file.
Publicizing more now-private methods.
