Support debug_url in the manifest

[Hacksore]

Is your feature request related to a problem? Please describe.
Currently, the focus of the project seems to be, develop in the browser and build for overwolf later.

Describe the solution you'd like
We should support the debug_url property in the manifest to allow for react hot reloading as well is reactive development within the overwolf client.

Describe alternatives you've considered
N/A

Additional context
tl;dr this is great for web browser base development but we should instead shift to allowing for development while in-game using the overwolf client.
