Changed name of SQL Server to avoid confusion

It appears that SQL Server causes some confusion among users as they
believe that it means any SQL database, not the Microsoft product SQL
Server. To avoid this issue, the display value has been changed to
Microsoft SQL Server. No backend changes have been made and it is still
stored as sqlserver in the database. This is only a frontent change.
