Create a template update script.

[seanfisk]

I have a number of projects on which work is currently being done that use this template project. It would be nice if I could run a script to update the project to the current version of the template project.

A possible solution would involve the following steps:

• Create a new "fake" project based on the template project.
• Replace the fake project's metadata.py with the old project.
• Run generation on the fake project.
• Diff the output on relevant files from the old project to the fake project and save to a patch file.
• Use git apply or plain patch to apply the patch.

Some conflict resolution would likely be necessary for most projects, but it would be much better than doing a manual merge.

A prototype script is currently working. Has to be developed into a full script and then added to the PPT distribution.
