Enhancement - Make output easy to read

[gaurav-nelson]

The current output lists filename ---> link, and status. Some links are red colored(internal links), with no explanation to why it is so. Follwoing is current output:

$ linkchecker openshift-docs/install_config/persistent_storage/

DONE: Some link failed

It would be great if we can improve the output to be more clear and cleaner. Something along the lines of following:

FILE: long/path/to/file/with/extension/filename.asciidoc
[Unreachable]   http://this.is.link/that/failed
[Unreachable]   http://another.link/that/failed
[404]                 local/file/link/ti/image.png

For the moment I have developed an easy improvement in the output. Please, check it out. I will try to add position of the errors found in future releases.

@sjimenez77 Thank you for the updates. The output is easier to read now. It will be awesome if the output is grouped by files as well.

@sjimenez77 maybe add hacktoberfest label to this?
