Use sequential loading and requests for all UI resources (#5013)

Browse Source 
* use sequential loading for all UI resources

- load common.js and style.css sequentially for all config pages
- restrict all requrests in index.js to single connection
- retry more than once if requests fail
- incremental timeouts to make them faster and still more robust
- bugfix in connectWs()
- on page load, presets are loaded from localStorage if controller was not rebooted
- remove hiding of segment freeze button when not collapsed
