hub: make results easy to interpret for users

[siteshwar]

The result page for each task contains different logs that are collected by osh worker. It could be confusing for new users to read and interpret these logs. The user interface for results page should be redesigned to make the logs easier to interpret.

This seems reasonable but this view is once again provided by kobo therefore the options to modify it are limited.

I think issue #133 is closely related.

Good idea, @kdudka! We can use the results field for this.
