Fix T95335 Bevel operator Loop Slide overshoot.

If the edge you are going to slide along is very close to in line
with the adjacent beveled edge, then there will be sharp overshoots.
There is an epsilon comparison to just abandon loop slide if this
situation is happening. That epsilon used to be 0.25 radians, but
bug T86768 complained that that value was too high, so it was changed
to .0001 radians (5 millidegrees). Now this current bug shows that
that was too aggressively small, so this change ups it by a factor
of 10, to .001 radians (5 centidegrees). All previous bug reports
remained fixed.
