serve could watch file and directory changes to auto-refresh browser

[henriquemattos]

Expected Behavior

I got used to webpack watch tool that listen to file and directory changes and trigger a recompilation automatically of the source code and triggers a browser refresh.

Current Behavior

(I assume) ui5 serve watches file and directory changes and they are available often it happens, but the browser refresh has to be triggered manually (ctrl shift r).

Steps to reproduce the issue

1. Run ui5 serve -o /index.html;
2. Change any file inside your project structure and save it;
3. Refresh the browser without the need of running ui5 build.

Affected components

• [ ] ui5-builder
• [X] ui5-server
• [ ] ui5-cli
• [ ] ui5-fs not sure if should involve fs
• [ ] ui5-project
• [ ] ui5-logger
