Fixes to the (Non)ConvexTesselation, working with 1_2_dimethoxyethylene

minor changes:

BoundaryLineSet::CheckConvexityCriterion() reduced verbosity
CalculateConcavityPerBoundaryPoint() moved to tesselationhelpers.cpp
FindNonConvexBorder(): flag -> OneLoopWithoutSuccessFlag, failflag -> TesselationFailFlag, N removed
FindNonConvexBorder() - CheckListOfBaseline() used before and after insertion of straddling points
BoundaryTriangleSet::ContainsBoundaryPoint() overloaded function to check also for TesselPoint
Tesselation::InsertStraddlingPoints() - LinkedCell only redone when point was added
Tesselation::AddTesselationTriangle() - overloaded function to set index of triangle directly.
new function CheckListOfBaselines() - outsourced from FindNonConvexBorder()

major changes:

BUGFIX: FindNonConvexBorder() - increment of baseline was missing
third step (Flipping baselines) removed from ConvexizeNonconvexEnvelope()
BUGFIX: BoundaryTriangleSet::GetIntersectionInsideTriangle() < should have been > in final if-statement to check whether in- or outside
Tesselation::InsertStraddlingPoints() - behavior of FindClosestTriangle() changed, hence we have to check whether returned triangle does not contain the point in question.
BUGFIX: Tesselation::FlipBaseline() - did not change LastTriangle which caused crashes on writing envelope, as it pointed to delete memory

Property mode set to 100644
