Add support for showing end location marker (#200)
* Add support for showing end location marker

* Cleanup Reportable method definitions

There’s no need for double splats, since they mess up method resolution, and obscure the actual - single (!) - argument - `status`, so… be gone

Also, all of the helpers return the constructed `Issue` like a behaving good methods.

* Refactor Util#affected_code

* Increase max length of trimmed lines to 120 characters

* Refactor Issue to use enum instead of a symbol for #status

* Optimize Reportable#valid?

* Add spec coverage for newly added Util methods

* Refactor DotFormatter a bit

Make text format moar in line with Crystal spec runner.

* Update README.md
