Provide support for building Dojo 1 code as part of a build instead of limiting it to being pulled in as an external.

https://github.com/maier49/cli-build-app/tree/dojo-support has an implementation that works on osx, but only because the html-loader has been commented out. If we want this we'll need to address incompatibilities with the html-loader. It's failing in the build time render plugin, but that's actually caused by an underlying issue that can be seen by disabling build time rendering. Specifically dojoLoader is undefined when it's called in html-webpack-plugin's evaluateCompilationResult method so it fails However, this only happens when the html-loader is in the config, otherwise it builds and runs successfully.

Additionally there's a new issue in Windows after updating to the 3.0 build code, where there are quotes that are not properly escaped in some request params.

Because of the number of build issues that kept cropping up with small changes to cli-build-app, as well as some issues with the way global objects are handled that led to problems with dgrid DnD behavior, we decided to drop the effort to build Dojo 1 sources as part of the build. Instead, the externals config in cli-build-app can be leveraged to include pre-built or un-built Dojo 1 code.
