added roadmap

So there is the list of what I have done:

Public Roadmaps and Feature Voting

• the roadmaap can have the status (Planned/In Progress/Done) and the Types (Feature/Bug/Improvment)
• the dev can Drag and Drop the items into the status it is in and also mdelete it.
• Users can comment and upvote those Items

Redesign of Game Detail site

• Its not 9 Buttons in one row anymore
• It’s seperatd into two sections.
• updated the sale section

And I also added Unit Tests.
