User information leaking through debug log prints.

adb logcat reveals several debug log entries marked with "GetRemoteUserInfoOperation". Here is one example.

02-09 23:12:33.410 28516 3060 D GetRemoteUserInfoOperation: Successful response: {"ocs":{"meta":{"status":"ok","statuscode":100,"message":"OK","totalitems":"","itemsperpage":""},"data":{"enabled":"true","id":"xxx","quota":{"free":110406975803,"used":50654297797,"total":161061273600,"relative":31.45,"quota":161061273600},"email":"xxx@xxx.xx","phone":"","address":"","website":"https:\/\/redacted.com","twitter":"@redacted","groups":["admin"],"language":"en","display-name":"Redacted"}}}

It makes sense to print these as a debugging measure, but it doesnt belong in a production ready deployment. My recommendation would either be to use a wrapper class to filter the log prints away from RELEASE builds or use Proguard to filter out the debug code completely.

I believe #118 is a better fix.
