changing font in theme should change font of comments and etc...

[porres]

this is related to https://github.com/plugdata-team/plugdata/issues/1671

and also https://github.com/plugdata-team/plugdata/issues/1656

The thing is that changing the font in a theme does change iemguis' label, which I discuss in https://github.com/plugdata-team/plugdata/issues/1671 that it shouldn't

On the other hand, as also mentioned in that other issue, comments, text in objects, message box and everything ELSE could and should change with the theme's font!

This is how it works in Vanilla by the way, and I think it's important if we want to create a Vanilla theme ( see https://github.com/plugdata-team/plugdata/issues/1656 ) where it should load the same font as used in Vanilla.

The theme font may also be recalled and used as the default font for [note], but a saved [note] object would have a hardcoded font type.
