Ipfs-companion: webui, url localhost:5001/webui wrong

[flowpoint]

when accessing webui via, "localhost:5001/webui", i land at the url but with port 8080.
so: http://127.0.0.1:8080/ipfs/hash/#/
instead of http://127.0.0.1:5001/ipfs/hash/#/
using go-ipfs 0.4.11 as systemservice with the ipfs companion extension 2.0.12

This is because extension thinks 127.0.0.1 and localhost are different things.

What if we normalize 127.0.0.1 on saving preferences and always replace it with localhost ?
It improves the Location Bar a bit; looks less scary for non-technical users.

@flowpoint No one picked this up, so I've fixed it in v2.1.1beta3, give it a try :)
