Mesh enhancements

[seriesumei]

I pulled these out of an earlier Issue (https://github.com/RuthAndRoth/Ruth/issues/14) and did not want them to get lost...

• (from @LucierdaSolari) I would like to be able to flatten the nipples on the breasts as well as the vagina on the Ruth mesh. I am a PG-13 person at most.
• (from @AdaRadius) @LucierdaSolari I've gotten quite a few requests for flattening nipples and groin in both Ruth and Roth - there was much debate at, I think, a Kitely meeting about a year ago. Some love Shin's nipple design, some don't. So I agreed to make two versions when I do the Blender 2.8 versions. Meanwhile, anyone who wants to do it in the current Blender versions will be much appreciated. :)
• (idea taken from the Maitreya Lara v5 body) Add panels to smooth body areas for use when wearing Bakes on Mesh system clothes laters, ie smoothing between breasts under a sweater, smoothing toes under socks, etc.

A trim of the area on the Ruth2 back under the arms, and a little bit on the bum is what I find usually sticks through Maitreya Lara shaped clothing. If someone who knows their stuff feels this area can be smoothed that would make more clothing options available in Second Life, and make compatibility elsewhere better too.

I tried that myself, and it worked pretty well! Those areas no longer stick out. :)

@AdaRadius is looking at the mesh shape fir the next version... maybe share your revised mesh with her... possibly via your contrib/name folder under the Ruth2 repository?
