Include a separate page for tagged articles

[ashokdey]

Hello,

This issue is w.r.t #12

Thanks for this amazing theme. I was able to configure it a lot but I am stuck at making a feature in which if I click on a tag it should take me to a new page with all the related articles of the same tag. I am still trying to make one, if I complete it, I will open a pull request but if anyone can do it quickly that would be really great!
