Tests don't run under Xcode Beta4

[rogernolan]

2014-08-18 11:32:11.836 otest[1198:157856] The test bundle at     /Users/rog/Library/Developer/Xcode/DerivedData/MMMarkdown-fekjtqpmnzjnpmemexluahtptwlw/Build/Products/Debug/MMMarkdownTests.octest could not be loaded because its Objective-C runtime information does not match the runtime information required by the test rig.  This is likely because the test rig is being run with Objective-C garbage collection enabled, but the test bundle does not support Objective-C garbage collection.  To disable Objective-C garbage collection for the test rig, run it in an environment with the OBJC_DISABLE_GC environment variable set to YES.

2014-08-18 11:32:11.838 otest[1198:157856] Couldn't posix_spawn: error 8

Xcode also complains about SenTest being deprecated so updating the test framework is probably the fix :-(
