Memo+ update v.1.20

1.20 version has two new features.From now on, iOS 6.0+ users can turn on synchronization with the server profile at any time. At all three levels (groups, sets and questions) there is "pull-to-sync" function which enables you to update all the data on request, throughout the app.
We've also introduced a stop watch which measures your answering time. Additionally, the app calculates the average answering time for each question and shows it in the question card details. If you do not want to use the stop watch function, or the sound effect which have also been added for more fun, you can turn them off in the full Memo+ version in the app settings.
A minor error related to the synchronization with the server profile, present in the previous version, has been corrected.
