#7 SMARTS matching in 2D rendering shows also bridging bonds

[Joerg Kurt Wegner]

Problem occurs in joelib.gui.render.Render2D: line 305

So, only atom are added to the rendering engine and it
draws then bonds to all neighbour atoms.
So, we need to add also the bonds obtained from the
SMARTS matching or more exact the bonds between all
atoms ONLY in the SMARTS matching and its correct order !
