Add fullPath option

[ghost]

Would it be possible to add a "fullPath" config option so that the paths sent to tslint are absolute instead of relative?

It is very useful, at least when using WebStorm, to have the formatters print full paths because they are converted to clickable links in the console.

Thanks, Andres

This will be also helpful with vscode

I believe this is now the case with TSLint 4.x
