Support custom reporters

[ajsait]

It would be cool if there will be a Jenkins integration

[segiddins]

@ajsait can you please give a bit more detail in what you're asking for?

We want to use the SwiftLint in our Jenkins CI server. Currently it just generates something like this.

Finding Swift files in current directory...
/Users/Shared/Jenkins/.jenkins/workspace/iOS-v3-Build/Foo/AppDelegate.swift:20: warning: Length Violation (Low Severity): Line should be 100 characters or less: currently 125 characters
/Users/Shared/Jenkins/.jenkins/workspace/iOS-v3-Build/Foo/AppDelegate.swift:21: warning: Length Violation (Very Low Severity): Line should be 100 characters or less: currently 117 characters
/Users/Shared/Jenkins/.jenkins/workspace/iOS-v3-Build/Foo/AppDelegate.swift:27: error: Length Violation (Very High Severity): Line should be 100 characters or less: currently 281 characters

/Users/Shared/Jenkins/.jenkins/workspace/iOS-v3-Build/Foo/AppDelegate.swift:37: warning: Length Violation (Medium Severity): Line should be 100 characters or less: currently 153 characters

It would be nice to have a much better report for SwiftLint, something like the one in Sonar.

I think this boils down to supporting structured output - json, csv, etc.

[jpsim]

Indeed, supporting custom reporters would be great!

[ajsait]

A PMD XML report file output would also be ideal.

[rompic]

Would be perfect if sonar could be supported

[jpsim]

Could those of you who have requested support for custom report formats point to official documentation for the formats you need? I'll need a full spec of what "PMD XML" and "Sonar" output should look like.

[jpsim]

I've added the infrastructure necessary for this, along with new JSON and CSV reporters in #133.

I encourage those of you who have requested this feature to take a look at how it's done and let me know if it's on the right track.

I would certainly add XML reporting to the mix, primarily because TeamCity, for example, can handle a lot of XML-based formats, but, unfortunately, neither CSV nor JSON.

Thanks for the suggestion @dmytrol, I've created #277 to track that.
