Merge branch 'master' of github.com:rmacy/EmmaSDK
- Issue preventing archiving of projects with EmmaSDK has been resolved
- Added getMyOAuthData method which returns a EMOAuthApplication object that has an NSArray called accounts and that object will hold EMOAuthAccount objects that only have a NSString call account_id
- Added to the requestGenerator code some logic that will use login.e2ma.net instead of api.e2ma.net when no accountID has been set.
- Fixed bug in createMembers, createMember and updateMember methods not including "fields" objects in post parameters
- Added signupMember method
