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 nightscout#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 nightscout#144  and add watch for overrides.

fix when preset has no id

Add override options for apple watch inside the temp target menu.

- allows to select a override preset (or a temp target)
- allows to cancel a current override preset or specific override (idem for temp target)
- add a color profil for override profil
- Fix some minor code

use async to update overrideObserver.

Keep the one in Nightscout Config

- One more click to reach the service, but
- Added chevron in settings list (for consistency)
- Added room for information/explainations of the setting in header/footer in the new view
- First draft to build on (maybe: rephrase header/footer, add connection status in navigation view, other relevant info etc)

- and remove uneccessary header

-and also tidePool* to tidepool*

- Footer text in 2 elements
- spelling error fix
 and Connect to Tidepool from ontapgesture text ->  Action button with blue text for consistency

- Sheet needed to be moved outside Form (Swift curiosity)

Treatments: Carbs and Temp Targets - and also announcements

- Imroved structure and UX workflow when configuring Nightscout settings
- Added Connect, Upload, Fetch views with relevant settings per view
- Import settings and backfill glucose buttons kept in rootview since they are more frequently used
- Added footers for many sections to explain what the toggles actually do
- Loacalizaation needed for new textstrings. Just updated that with small changes in already existing strings

- Break up long strings in several text elements (enables re-use of some already existing translations)
- Change button text "Connect" to "Connect to Nightscout" in NightscoutConnectView

Display the eventual Pump Statut Highlight Message in home view if state is warning or critical.
