Override or extend autocomplete default classes

[slolo2000]

Hello,

It would be nice to have a way to override (or extend) default classes in order to customize the result as we need. Moreover, we such option, we could make the component easily compatible with framework like bootstrap, ...

For example, if we are able to replace "autocomplete-group" by custom one, we could have "bg-primary my-custom-class ..."

This feature would be really useful I think.

Thanks in advance and have a nice day.
