Swhatch reset option in menu

[Zdele1]

With swatches being saved on closing photoshop, I feel there is a need to have an option to reset swatches back to defaults (only one swatch, grey), so that there is no need to manually click each swatch and hide it. And hidden swatches still remain in the panel, which might not be relevant to the new project.

It could be in this menu, to reduce UI clutter
