Switches to the already committed new cxxtest sources and deletes the
old sources.
Applies the changes from 6374080b60 and 4a57fed5a7 to the updated
sources.
Replaces the cxxtestgen.exe for Windows. This file was created from
cxxtest's python script using pywin32.
Modifies update-workspace.sh to force a rebuild when cxxtest options
could have been changed during the premake step.
Adds an additional option (--jenkins-tests) to
premake4.lua/update-workspaces.sh to use cxxtest's XmlPrinter which
generates output than can be used by Jenkins.
Fixes#2450
