Allow custom spinner via config file

Allows to set `ui.spinner=` to a string which is then split by
`ui.spinner-delimiter=` (Default: comma) instead of having a hard coded
animation.

This implementation doesn't use INIs capabilities to split strings as
it trims whitespaces breaking the default animation.
