[LDView] LDView 4.4 Beta 4 test release

[Travis Cobbs]

Much appreciated changes. I'll keep my eyes peeled to see if this causes other problems.

Thanks. Just to be clear on the change, I updated the code that processes conditional lines for use in smoothing, and made it so that if there is an edge line in the same place as a conditional line, it ignores that conditional line during smoothing. This was a relatively minor change, and while it will affect file loading somewhat when smoothing is enabled, hopefully it won't be much. Also, it means that if an edge line partially overlaps a conditional line, the conditional line will still be included in the smoothing calculations.
