Fix, NSBezierPath, appendBezierPathWithArc...

[Georg Fleischmann]

Hi,

here is a little patch for [NSBezierPath appendBezierPathWithArc...].
It draws a line segment to the start point of the arc. A move is only used if  
the arc is the first element in the path. This makes the method more complient  
to the PostScript specs, and is needed to make complex paths work at all.
