feat: Add UI configuration for custom favicon

[mloskot]

Adds new node favicon to ui configuration with properties that allow to overwrite the three favicons which are currently in use in the index.html template.

Configuration Example

ui:
  favicon:
    # these are all optional, can be mixed and matched
    default: https://example.com/favicon.ico       # replaces default /favicon.ico
    size16x16: https://example.com/favicon.ico     # replaces default /favicon-16x16.png
    size32x32: https://example.com/logo-32x32.ico  # replaces default /favicon-32x32.png

Any reason why this has not been merged? I would appreciate if I could easily change the favicon.

@mloskot Could you add a quick test for the new feature?

Sure, I can try. I see there is also a conflict to resolve. Please, give me 2-3 days and I will deliver an update to this PR.

@mloskot No problem, take your time!

@TwiN I've resolved the conflicts and force-pushed to update this PR. I see there is a change to ui_test.go. Is there anything else to cover with tests?
