PathTraverse does not check vertices

[Crimson Wizard]

When using PathTraverse there's a chance that line get straight through the vertex or a number of vertices. It seems that in that case no line(s) are counted intercepted. This may lead to unexpected results especialy if these vertices were joints between solid lines.
I believe this could be fixed somehow, for example checking all vertices in each passed sector to find these that lie on the traversing path... or maybe there are better ways.

Couple of extra notes.
First of all, I found that this effect happens sometimes when vertex does not seem to lie right on the traverse line, but very close to it as well.
Secondly, now I recall that there were moments in various games when missiles shot into the room corner dissapeared; now I guess they just passed through wall then.
