app(chore): upgrade to ng5

[axtho]

• upgrade the core files (depends on Angular 5 support ngrx/platform#538 to be resolved)
• change build of core library to fit ng5 (either Support Angular 5 jvandemo/generator-angular2-library#230 gets solved or we adapt https://github.com/filipesilva/angular-quickstart-lib)
• upgrade web
• upgrade mobile
• lint web with new cli linter
• resolve Observable issues with the HttpClient

For the ngrx part errors seem to be in module decorators and lambda functions. Caveat emptor, here be dragons but if you are not using decorators on the store it should work ( at least for us it seems to work with Angular5 ).

@MattiJarvinen-BA you mean decorators like @effects, etc? Thanks for the heads up.
