Do not redirect IPFS resources if hostname is 'localhost:*'

[lidel]

<deni> IPFS desktop opens localhost:5001/ipfs/[hash] and companion redirects to localhost:8080/ipfs/[hash]

Background

This does not happen in companion alone, because it normalizes localhost to 127.0.0.1 to avoid mixed-content warnings in we browsers, and we already ignore gateways at 127.0.0.1.

Test Link: http://localhost:5001/ipfs/QmQLXHs7K98JNQdWrBB2cQLJahPhmupbDjRuH1b9ibmwVa/

Fix

U guess we probably should do both:

1. Companion ignores gateways on localhost
2. Desktop opens links with 127.0.0.1 instead of localhost

@hacdias thoughts?

@lidel I think it would be better for Companion to ignore gateways on localhost. I know Electron can register specific protocol handlers (like ipfs:// or dweb://) but as far as I've searched, I can't find information on how to open 'regular' URLs for a specific domain, which leads me to conclude that it is not easily possible.

@hacdias what I meant was to normalize localhost to 127.0.0.1 in API and Gateway port settings.
Eg. if user enters API port as localhost:5001, it should be replaced with the IP version.
(but yeah, on top of that, Companion should ignore localhost )

@lidel gotcha! I agree then 😄
