Add more detailed logs

[yuriescl]

When clicking "Download logs", I get a log file with the same generic information displayed in the page.
It should contain more detailed logs.

For example, when the CORS header ‘Access-Control-Allow-Origin’ is missing, it just displays a TypeError: NetworkError when attempting to fetch resource. in both the webpage and the logs.

But in the browser console we can see a more detailed message: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://<domain>/.well-known/stellar.toml. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

If possible, please add this kind of detailed message to the logs.

Unfortunately that is the one piece of detailed information we can't add (i wish we could!) the browsers don't allow you to see anything about CORS headers if CORS fails, this is for security purposes.

We can guess though, and if there's any network error put a note that says "Make sure CORS is enabled [..details]"

@msfeldstein Another idea is to print the transaction (sent via postMessage by the popup) in the page, console or logs.
