0025455: fixshape works at the second attempt

Added check and fix of tolerances of all vertices after performing all fixes.
It is necessary to avoid situation when point of vertex belonging a few faces was changed for current face
but edges containing this vertex belonging before fixed face are not taking into account.
Mode FixVertexTolMode to manage check tolerance of vertices was added in ShapeFix_Shape
class. (default value is equal to -1)
Method to change FixVertexTolMode mode  FixVertexTolMode() was added in ShapeFix_Shape class
