support sym-links in WARP signature resolution

[psifertex]

it would be nice during testing if it were possible to sym-link plugins into the warp signature folder.

What plugins, warp expects warp files in that directory? Or are you talking about extensions supplying warp files? The solution is redesigning the extension stuff to have “mounts” where plugins can place files, and then keeping track of who “owns” what files for updates and removals.

Sorry, that should be "signatures". I don't think we have to make a full on mount system, that seems like an over-engineered solution to a simple request. I'm using a separate plugin to generate and test various signatures. Instead of copying them into the signature folder it would be nice if I could generate them elsewhere and simply link them in. This is especially true when I'm testing with multiple user-folders.

Much like how my user folder currently contains a bunch of sym links to python plugins that I'm writing/testing that live in another location but I want them to also be loaded by BN.

What happens when the plugin is uninstalled that made the symlink?
