[Feature Request]: Better reroutes (Blender-like)

[catboxanon]

Moved from discussion in #301 (comment)

Not to get terribly off-topic in this PR, but I think it may be worth considering looking at how other applications like Blender handle this, which supports creating multiple links at once (often for the purpose of grouping a single output going to multiple inputs), and more importantly, in a less mouse-precise way (node links are quite thin and require cursor accuracy). The same tool can also be used to quickly remove links.
