Install IdB MIM Adapter DLL to appropriate MIM directory

The MIM adapter currently installs to a Unify directory in Program Files, after which it needs to be moved manually into the appropriate MIM Directory.

The installer could install into the appropriate directory, which would result in better end user experience, both in the initial install and in repairs.

The FIM Sync base directory can be retrieved from the registry at: 

SYSTEM\CurrentControlSet\Services\FIMSynchronizationService\Parameters\Path

as documented here.

After this \extensions needs to be added to the path value to find the location.
