Benjamin Smedberg 84f471652b Bug 602891 part B - Backend support for jetpack-process crashes and crash recovery, r=cjones
On crash, an event will be submitted to the parent with the name "core:process-error" with a context object. If crash reporting is enabled and a crash report is available, the context object will have a .dumpID property which can be used to submit the crash report.
