Allow reroute to have in/out in different orientation

[Davemane42]

took into consideration old workflows and convert the node after its configured.
also handle the old vertical/horizontal setting.

added reroute to the canvas right-click for easy access.

nice one thanks

[pythongosssss]

Nice!

Found a couple of small issues:

1. Add reroute -> Show Type = Crash this.getDisplayName() is undefined
2. Have workspace prior to this version with a reroute where the name is showing
   
   Update to this version
   
   Double text

[Davemane42]

@pythongosssss Double text should be fixed, cant really reproduce the undefined function

[pythongosssss]

Hmm, odd I can reproduce it on a fresh colab instance by:

1. Add a reroute
2. Right click, Show Type -> Crash
   

Also crashes via

1. Add a reroute
2. Right click, Show Type By Default
3. Add a reroute -> Crash, cant add reroutes anymore

@pythongosssss I was thinking it was a colab only bug but i loaded up a fresh install with the branch and it just worked, no error.

I get the exact same bug as pythongosssss. It happens in both firefox and chromium for me on your exact branch and a clean browser.

I've looked at the code again and i cant really tell what it is. ComfyUI is my first foray into Javascript and i really dont know what m doing wrong here.

tested with edge, chrome and firefox with no error

I can see the 2 errors and ill rework these part after a night sleep but its all guessing on my part after this

I tested this PR and extended it a bit. I allowed setting the orientation of input/output to any direction and if there's overlap they just swap.

I also made it possible to add multiple slots to the reroute node (input 1 goes to output 1, 2 to 2, etc).

In on mobile now so I can't post the code, but I can get you a diff later.

The multi-output support could probably be used to implement the "bus" functionality requested elsewhere too if you just add a mode that copies one input to all outputs.

@Davemane42 This branch has a couple patches on top of yours: https://github.com/asagi4/ComfyUI/tree/input-orient

It's probably not perfect, but I wasn't able to immediately break things.

I worked around getDisplayName returning nulls by just making sure it never does... This probably changes the title display behaviour a bit, but at least it doesn't explode.
