WIN build xcerces binaries

[michaeldsmith]

The current WIN build instructions says:
download xerces c++ from http://xerces.apache.org/mirrors.cgi and build using MSVC

I don't think building xcerces from source is necessary, it seems simpler to just download xcerces binaries.

xcerces binaries are only available for up to version 3.1.1, but the latest source is 3.2.3. Does jid need the latest?

If 3.1.1 is OK, then I suggest changing this instruction to
download xerces c binaries v3.1.1.1 from https://archive.apache.org/dist/xerces/c/3/binaries/

I used this this one and it has worked great:
https://archive.apache.org/dist/xerces/c/3/binaries/xerces-c-3.1.1-x86_64-windows-vc-10.0.zip
