Add support for LogHash logging

[cmaneu]

Hi,
I work with @labynocle. We started to use Tailon on our logs and we like it so far :)
We would like to add syntax coloration for LogHash logs (see https://github.com/cmaneu/loghash-spec/blob/master/loghash-spec.md).

What is the best way to contribute this feature (it's frontend only)? I didn't see any plugin architecture and It may be not appropriate for everybody :).

@cmaneu I think if tailon implemented regex based syntax highlighting it would fit your needs. I made a feature request in gvalkov/tailon#14

I'll Followup the feature request #14 and see if it's works for LogHash :) Thanks !
