Small styles UI tweaks

- fixed a typo in bim.select_by_style
- added note to clarify what Shade/Render/Texture/Lighting/etc buttons do and moved style selection block at the beggining (maybe it's just me but when edit buttons are above selection ui it seemed like they affect all the styles somehow, not just the currently active one), so it will be more intuitive
