[ticket/9725] Create an Azure SQL compatible Schema

Two problems were encountered when installing on AzureSQL:
-Azure SQL does not support the ON clause of T-SQL
-Azure SQL requries a clustered index AKA primary key on all tables

The fix is makeshift; it introduces questionable primary indices, which should be replaced with auto--increment columns.

[ticket/9725] Add dummy indexes for Azure

SQL Azure requires a primary AKA clustered key on every table.
This adds a dummy INT column to act as key,
avoiding possible duplicate entries.
so that these columns can support bigger (speak: huge) tables
