Using non-expiring access_token instead of refreshing expiring access_tokens. This is just for the SoundCloud service. See this: http://stackoverflow.com/questions/12976912/unable-to-refresh-token-after-expiration.
Don't need the '.json' extension as explained here: http://soundcloud.github.io/java-api-wrapper/javadoc/1.3.1/index.html?com/soundcloud/api/ApiWrapper.html
Throwing exception if something wrong occurred when asking SoundCloud for protected resources. This way we avoid the 'connected' badge when the user is not connected to the service because of an expired access_token.
Translating the connected badge.
