Responsive rendering, related to #7

[bearfrieze]

Implemented responsive rendering as suggested in #7. I tried making rendering more flexible while I was at it.

I had to alter the normal/wide/horizontal view a little to fit into the more flexible rendering model, hope you don't mind.

Equal to or greater than 125 columns:

Less than 125 columns:

Until there's a version with responsive rendering implemented, we can use less to make the output horizontally scrollable:

$ wego | less -RS

Now use the arrow keys to scroll right and left.

+1 to this pull request. Another interesting to have would be a command line option to actually define the format (overriding terminal size detection)

@marado there is already a working split of the backend and frontend in the issue1 branch. Note, that It requires Go 1.5 and I also want to clean up the interface between backends and frontends before merging to master. Then this PR can be merged as a separate frontend.

This branch seems stale. If anyone wants to pick this back up and rebase it, feel free to do so.
