Start moving win-setup to PowerShell.

Add win-setup.ps1, which duplicates the following tasks performed by
config.nmake + Makefile.nmake + win-setup.sh:

- Create the windows library directory.
- Download files.
- Download and unpack zip files.
- Check and set current-tag.txt

Don't verify applications or libraries. CMakeLists.txt does that.

Update the Developer's Guide.

Have POWERSHELL_COMMAND use dot sourcing instead of "-File", which
appears to be a synonym for "-IgnoreTheExitStatusReturnedByThisScript".

This removes our dependencies on unzip and wget and reduces our dependency
on bash.
