[Therion] XTherion: Line simplification

In most cases it does, but if the points in a line are too many it still
leaves more points than I would like. And some remaining points are still
very close together because the line segment had some micro-curves that the
Bezier lines tries to preserve.
In other cases "Conver to curve" doesn't work and does nothing, but I
haven't checked the code to see why.

Sometimes I just need a simple "rougher" line without curves so I added
this option.
