Neuromantic V1.6.2 now available!

OK, I have uploaded Neuromantic V1.6.2 to the site - I've made sure the ZIP file works this time, also ;)

V1.6.2 mainly adds some bug fixes and minor features over V1.6.1, and I'm quietly confident that I've finally squashed the horribly annoying byzantine error that I've been trying to track down for several releases.

I've altered the selectable bounding boxes on compartments so that they're now the entire width of the compartment, rather than always 10 pixels either side. Lone nodes (with parent nor child) also display their radius now in the form of a circle around the midpoint, and it should be easier to select/drag around the root soma point of a tree that's surrounded by child compartments.

Another handy addition is the ability to press Ctrl+W and cycle through all the currently selected segments. This could be useful when correcting trifurcations or similar.

In terms of semi-automatic reconstruction, a median radius filter operation has been added that helps compensate for radius estimation errors. The radius of each compartment is simply calculated as the median of the estimated radii of a 3 compartment neighbourhood along the neurite.

It's also now possible to Autoselect overlapping points i.e. points that have exactly the same coordinates as another point in the tree. It was primarily added for Duncan Donohue, who's currently administrating the NeuroMorpho archive, and shouldn't be needed in the standard course of a reconstruction. In the case of overlapping identical subtrees, it will currently just select one of the subtrees arbitrarily (depending on ordering in the list). I believe that it should select entire overlapping subtrees due to the way the tree sorting algorithms work, but it's conceivable that in some circumstances it will select some from both - let me know if this happens.
