Maintain links consistency

[john0isaac]

@leestott around QA automation

Apply rule for regex to pick up the paths:

• relative URL cannot start with (/) it has to either start with (./) or (../)

Fix for the GitHub pages (refer to #92)

• @kinfey the .MD file in lesson 03 didn't work on the deployed GitHub pages before so, I renamed the file and changed the reference to it. please review

@john0isaac I think your proposed changes of ../ in front of relative links may cause issues for the GitHub pages deployment can you test this.

Thanks @john0isaac
