Updated to angular 5
Nothing that interesting. We use using their old and new HttpModule (old) and HttpClientModule (new). Should move to the new one in api.ts at some point. I had to add HttpClientModule to three component tests and I'm not sure why. They don't appear to use anything http related.
Nativescript doesn't support angular 5 yet - but I moved android back to 1.4 so we can focus on bugs and the invite system in 1.3. So shouldn't matter.
