Dependencies

[JAJames]

As a developer, I want to have a dynamic list of dependencies so that I can control dependencies in a generic way.

As a user, I want to be able to reinstall dependencies, in case there is an error.

Acceptance Criteria:

• [ ] "Reinstall Dependencies" button in Settings menu
• [ ] UE3Redist.exe be removed as hard-coded value
• [ ] Add "Dependencies" array of objects in version JSON file under "game", including UE3Redist.exe
• [ ] Each dependency object includes: Name, URL (Relative)
