Bump target to iOS7, introduce nullability, always async, and separate storage from queue

[gelosi]

Hi! Have a look please

I've updated README accordingly. Idea is:

• introduce QueueJob to avoid direct using NSDictinary for creating jobs (plan to add to Job max retry times, expiration date, fire date, etc)
• introduce nullability to prepare for Swift migration
• decoupling storage from queue using EDQueuePersistentStorage brotocoli :)
• adding some basic tests on top of that (to be continued)

Very cool. Taking a look now.

Overall this is great. Thanks for pulling this together @gelosi . I left you a few comments and notes for discussion.

Hi Andrew

Cool! Thank you for a quick feedback. This is a very start. I will try to offer some idea on 'built-in' persistent storage. As I suppose apps which using  already some sqlite wrapper different from FMDB might stay aside. That is my approach. Ideally - having ready-to go fmdb submodule (as default dependency). And reduce persistent storage interface requirements to CRUD :)
