to give more information about unreachable sites
When there are sites that are unreachable by feedly, user don't have clue what was wrong. eg. http://feedly.com/i/subscription/feed/http://www.radiomaryja.pl/feed/
I am able to read the address (downloaded file in attachment), Opera Browser was able to show the feeds news, but not Feedly.
Feedly displays it as "Unreachable", but user don't know if feedly cannot connect to the server, the format of RSS is wrong (like whitespaces before <?xml> tag), or there is 404 error.
Other site was also in "unreachable" state, but there was change in the RSS feed address.
