Sample universal smart store application.  The application will retrieve account and opportunity information from the server and store locally.  Demonstrates how to add data to smartstore, clear data, and how to retrieve it.
More code cleanup and updates to the sample.

Fixed some DB locking issues around large selects & drop statements.
Simplified login flow for single user; account manager is only presented when there is at least 1 account already logged in.
Login flow can be customized: app name, logo, and background color can be set.
Adding error dialog, fixing up sample container app to be more like a sample.
Adjusting sln structure.
additional preqeq for sqlite.
