Updated docs related to vscode and my old xunit formater

Cheers, will get this into next release once I'm done going through all the open issues 👍

@lfrodrigues is this line correct?

template = '%(line)s,%(character)s,%(code)s,%(code)s:%(source)s %(message)s'

It duplicates the code, so error messages end up like

1,0,unused-import,unused-import:pylint Unused defaultdict imported from collections

unused-import is in that line twice. I have no idea about vscode so dunno if that is correct or not.

I built the vscode for this also: DonJayamanne/pythonVSCode#130

It was designed like that because vscode expects to have:

const REGEX = '(?<line>\\d+),(?<column>\\d+),(?<type>[\\w-]+),(?<code>[\\w-]+):(?<message>.*)\\r?(\\n|$)';

From what I understood type was not available in prospector so I coded it like this. Ideally in type we should output something like the "category" in pylint. Is there a simple way to get that?

@lfrodrigues there isn't really a "type" value from any of the tools, unfortunately. I suppose you could use the source value instead but if it's fine as it is I will leave it alone :)
