Override refactoring and additional functionnalities

[avouspierre]

The PR includes a large refactoring of the swift part of override/profile functions :

• Override is stored in override core data, including history
• Override preset is stored in overridepreset core data
• Add the display of the override in main graph
• add the upload of override as a exercice in Nightscout - Fix #145
• improve the management of indefinate override / stop of indefinate override
• modify the code to respect the Ivan’s patterns of the app :

• Use of swiftInject (dependency injection) with the use of protocol class in the code
• Use of MVP principes, in particular not use of direct coredata in view class
• Use of a proxy model class between coredata and the app to manage changes of core data
• Use of the pattern of observe to refresh data/view/uploads

• add a core data unit tests allowing to add tests for coredata with a in-memory datastore for tests.
• test for overrideStorage available

This PR do NOT change the logic with oref and the interface of override informations in oref. This PR do NOT require a update of trio-oref code.

TODO : Changes the shortcuts after merging with PR #144 and add watch for overrides.
