Allow urls for files to be relative to a common base url

[AdmiringWorm]

Expected Behavior

Allow for a base url variable to be set in the configuration, which would be prepended the urls of the files themself if they aren't an absolute url.

Current Behavior

Currently, if you only wish to use files from a different repository and it has the exact same file structure, you'll need to edit every url in the configuration.

Possible Solution

Read a base url variable and store it, then read the url/path for the file the user wishes to download. If that url/path isn't an absolute url, then append that path to the base url.

Context

Makes it cumbersum to use the extension if you wish to use a different repository with the same file structure.

Your Environment

Not really relevant, as it isn't a bug.
