SnClient initialization revamp

@gallayl commented on Mon Apr 10 2017

Problems:

• Some config variables and methods (e.g. serviceToken, siteUrl) are stored globally, or statically on per-module-level
• The current ODataApi depends on the Ajax implementation from RxJS
• The current architecture doesn't allow a client to interact with multiple Sense/Net sites

Expected behavior:

• Create a more generic, non-static Sense/Net Client Service architecture
• Rewamp initialization / configuration logic.
  • Services should be configured on institation
• Make the Http layer 'providable'
  • Allow to define global headers on service level ( #7 JWT authentication prerequisit)
  • Allow to use Promise beside RxJs's Observable
  • Allow to use a 'mock' HttpProvider (for testing purposes)

Linked issue: #7

Update:

• We should move as mutch build logic from Gulp to NPM as possible to reduce depending from external packages (e.g. gulp-typescript, gulp-typedoc, gulp-rename, etc...)
• Allow to use Promise beside RxJs's Observable - We can not provide a type-safe API whitch supports both Observable and Promise, so we will continue to use rxjs Observable for the HTTP Api

• [x] Update Typescript Proxy Generation (remove internal export module)
• [x] Check / update readme (typedoc) examples
• [x] Update exampe codes (e.g. https://www.sensenet.com/for-developers - js example)
• [x] Check / update sn-redux dependencies
• [x] Code Review
