pginstaller - pginst: Initdb integration code.

Log Message:
-----------
Initdb integration code.

Only works on Win2000 and newer. There is no "nice check" for that now - it will exit out with a message about not
findingCreateProcessWithLogonW. 

Also, rename ValidateLocale@4 to ValidateInitdb@4, because that's what it really does.
