Subject: * Fixes mantis mantis 0006803 [PGSQL] - Simulator crashes -
 Mono.Security.dll missing.    The root of the issue is that the Postgres
 driver relies on Mono.Security.dll from the mono project.   Unfortunately,
 when using Mono, including the dll in the distribution causes conflicts. 
 This solution puts Mono.Security.dll in bin/lib/NET/  and, if windows .NET is
 the runtime, informs the assembly loader to load
 bin/lib/NET/Mono.Security.dll when .NET is scanning for the Mono.Security
 namespace.   On Mono, the included Mono.Security assembly is ignored.
