Have a better UI for error handling for IPFS

[jamesray1]

System information

AKASHA version: 0.6.1

Operating System: Ubuntu 17.10

Actual behaviour

Well, actually, it says "Synchronization completed" below the loading circle, but the loading circle is about a third filled, and when I click the next button, it comes back up again after a couple of seconds. I tried to turn IPFS on manually, but it also turned off again.

I checked the logs, which had an error:

Error: serveHTTPGateway: manet.Listen(/ip4/127.0.0.1/tcp/8080) failed: listen tcp4 127.0.0.1:8080: bind: address already in use

Expected behaviour

The error should be coloured in red. There should be a popup window after clicking the next button or after turning it on manually, at the least outputting the error(s), verbatim, and better yet giving a suggestion on how to fix the error. In this case, change the port from 8080 to something else, e.g. 8081.

Steps to reproduce the problem

Have something else running on port 8080, and try to run a fresh install of Akasha.
