Configurable webserver title element

[FinnHoller]

When users manage multiple services at once, it would be useful to be able to distinguish them by the webpage title (displayed as text on a tab).

A new configuration option could be created, where the service creator can overwrite the default title ("pydase App").

Possible Implementation

Provide <title> element with an id tag. In React rendering, replace the content of the title element by a user specified one, with a fallback to the default.

The user could specify his desired title in web_settings.json, for example with the key name "web title", because the full access path of a Python object can never contain spaces.

For now, #132 implements sensible defaults of the browser tab and navbar titles (i.e. the name of the service class). Further configuration is not yet planned.
