MOBILE-2986: ObjectiveCMIS/AlfrescoSDK fix for uploads consistently failing on iOS 8 (previous workaround has been removed)
MOBSDK-766 and MOBSDK-769: 4.2 Community servers now use the legacy OpenCMIS atom binding rather than the public API URL and the workflow definition API failing no longer stops session creation, the workflow flags are set accordingly.
