Allow certain WDI properties to be overridden by system environment variables

[GoogleCodeExporter]

Often, DB connection settings across various development environments (like, 
home or office) differ in some aspects. Having to modify WDI file to 
accommodate these changes is not an option, since it might accidentally be 
committed to the source control repo, thus causing all sorts of trouble.

What's required is this. Specially formed environment variables should override 
parameters in an WDI file.

"WIZARDBY_HOST" overrides "host", "WIZARDBY_PLATFORM" overrides "platform", etc.
