Performance Updates#51

Currently, Scrintal applications suffers from several performance issues, such as:

• The initial load of the application takes too long. It downloads user’s entire archive before the app is ready to use. This could be done in the background and the user can start using the app right away with the data that is synced so far.
• The performance might degrade in the subsequent launches after the first login, if the individual card sizes are too long. This could be solved with more efficient storage and parsing mechanisms.

Option to store card on the local drive/folder instead of in the cloud for desktop app can improve the performance to the great extent as this needs only sync for updated cards only
