Add a configuration to avoid word-wrap

[ZeeD]

Most of the times the visualization of the json is good.

Sometimes I need to deal with jsons with very long strings, and I would find very useful to disable the automatic word-wrap.
I would like to have a button in the webpage or a configuration inside the plugin to toggle the behavior.

For now I used as a workaround to just change the css and add a '* {white-space: nowrap !important}' (yeah, I know it's ugly)
