Restore support for custom reporters about specta

[nerdyc]

The default reporter format that I built breaks Xcode's test integration in Xcode 5.0.1. Since Xcode seems to be finicky about the format, Specta should modify the output format as little as possible by default.

I'll work on restoring this feature, but the new format may be much closer to Xcode's default.

My commit above re-adds support for custom reporters, but the format has changed to be compatible with Xcode's test integration features.

This is a much simpler implementation than the original. SPTReporter is simply a subclass of XCTestLog so its output should track any changes made by the Xcode team. As just another observer, it should play well with any 3rd-party observers too.

The only non-standard aspect is that I was forced to swizzle -[XCTestLog startObserving] and -[XCTestLog stopObserving]. There was no other way to force XCTest to use SPTReporter without requiring users to explicitly add the -XCTestObserverClass default to their test scheme.

Great stuff! That works a treat 👍

Related: we should have an open radar issue filed publicly that people can duplicate and submit to Apple's Bug Reporter asking for more flexible test support in Xcode. It seems to me that Xcode is heading in the direction of more fully supporting differing test syntax like that Specta uses, but duped radars help get issues like this more attention.

Is there something already written that we can use? It might be good to promote something like this — I'm sure the Kiwi guys would get behind it too.

Tested out d4b1e27 in my project. Seems to be reporting the pending and focused tests correctly!

it seems like this breaks current workarounds to get code coverage reports on iOS7, like http://qualitycoding.org/ios-7-code-coverage/ .

Has anyone had success getting these reports to run in combination with specta?
