backport to ios7.1

[michaelkirk]

Can't deploy to ios 7.1

Need to change deployment target, and address any backwards compatibility issues.

• new warnings in main.storyboard
• xcglogger requires ios8, the recommended workaround is to not use the "module" but to include the source directly.
• alamofire requires ios8, the recommended workaround is to include the source directly, and resolve and wrap any called methods in a public struct. See here: roadfire/Alamofire@22e893a

This has been deprioritized since I no longer have an ios7 user.
