Proposal: add Style Name below each style preview image in the Styles panel

[feragnoli]

well … it's pretty much all in the name (title), I guess.
Style icon look nice and fancy but … rather obscure (especially in cases one were to be 'tweaking' different versions of the same style). That fact is made even worse since the editor does not seem to display any preview image at all for a style that it has saved but somehow still considers empty.
