Wire end "blobs" overlap and are almost impossible to click

[Elijahg]

When using a component with fine pin spacing, it's very difficult to click on one specific wire-end "blob" since the blobs overlap, and scale up with zoom level. The blobs should scale down when near other blobs, and/or scale up at say half or 1/4 the rate as the rest of the PCB as you zoom in.

This is still valid (Version 0.9.3b and develop branch)
