Make 15.x code base compilable on Windows

brXM 15 is not compilable on Windows locally.

1. npm integrity issue on cms/api and channelmanager/ui

   [INFO] npm ERR! code EINTEGRITY

2. line end issue in org.onehippo.cms.json.JsonTest and other unit tests
3. in community/channelmanager/ui, tslint "file-header" "enforce-trailing-newline": true doesn't work
4. in enterprise/wpm/frontend/project-management, "npm run lint" doesn't work due to linebreak differences (CRLF vs. LF)
5. cannot build enterprise/replication/integration/tests nor similar enterprise/replication/integration/tests because of failing integration tests during normal build (mvn install)
6. cannot build enterprise/targeting/state/elastic7 because it downloads a Windows-specific Elasticsearch for an integration test, which fails

The SaaS branch is compilable on Windows, so this should be fixable.
