Added build validation script and called as part of the windows cli build.
Removed the appInitCmd and call the same preInitCmd code for all
interpreters. Guards in the boot.tcl script prevent reinitialization
of vfs code. This is required to ensure that all child interpreters
and also any thread package interpreters can be initialized correctly.
Checked both tclkit executables and with a basekit dll using the
validation script.
