I used semi-automated methods to triage and disable the initial b2g desktop mochitest failures. It turned out that many of these failures had nothing to do with the tests themselves, but were caused by an intermittent crash in the platform. The crash got fixed in bug 924681, but I landed the tests disabled anyway to get the rest of them up and running faster. Now I should go back and figure out which ones are safe to re-enable.

This patch is green on cedar. There are probably some other tests that could be re-enabled, but this is the best I can do without starting the triaging process from scratch again.
