build tools need to create per-package rollup files in addition to root package files
Today, it is onerous and/or penalizing to use dojo via <script /> tags.
After discussing the problem in some depth with David, we have decided that the build system needs to be extended/fixed to automatically build "sub-directory rollup" files which is something the package system is already designed for. Additionally, these files should be preceeded by dependency checking code which uses document.write() to add <script /> blocks for including per-module dependencies. The end goal is to allow less-clued developers to include the parts of Dojo that they want in a coarse-grained way using only <script /> tags.
