Rename geomechanics?

The geomechanics folder contains (solid and poro-)mechanics models. The models are more general than just geomechanics. Maybe move to mechanics or to make that clear? Better name?

I know that mechanics often abbreviates solid mechanics, but since we are doing a lot of fluid mechanics, I would opt for solidmechanics.

Maybe we should do a split into solidmechanics (elastic, hyperelastic, hyperviscoelastic (coming up next release)) and poromechanics (el1p, el2p, hyperelastic1p (planned)).

Would be good to do this before the release because headers will be duplicated for the release with "#warnings" and can then be removed after the release.

fyi @Maziar

I'll have a look.
