EDD-10: Send user to EDL to accept a EULA when necessary

[macrouch]

Overview

What is the feature?

When EDD detects a EULA needs to be accepted, it will open the user's browser to EDL with a redirect_uri provided by the initiating application (EDSC). After that application opens EDD again, the download will try again.

This PR also adds some more useful information as errors when a file fails to download.

What areas of the application does this impact?

Downloading files behind a EULA

Testing

Reproduction steps

Initiate a download from EDSC for files behind a EULA, with a user that has not accepted the EULA. After accepting the EULA EDL will redirect to EDSC, which will open EDD and continue downloading files
