adaptive_cloth: AdaptiveMesh: flip edges: set edge size

It is important to set the edge size for all the newly created edges.

Limit the number of loops, it can easily become an infinite
loop. There should be a better solution for this but cannot think of
one as of right now.

Always check if the edge is still flippable or not. Again, this
couldn't be solved with a different flip edge algorithm where the new
edge is always added, but right now, that isn't possible.
