Add a route to read word page

[raulfdm]

Must be created a route to receive a param with a world name and provide the following information:

The URL to consult is:

https://secure.tibia.com/community/?subtopic=worlds&world=<WORLD_NAME>

Important

• First letter of world param must be capital letter. (amera !== Amera)

I could help with this :)

About the world name: I think it could be normalized, this way we can handle amera, AMERA, aMera, etc.

const normalize = (name) => 
  name.charAt(0).toUpperCase() + name.slice(1).toLowerCase()

// normalize('aMera') -> 'Amera'
