Managing updates

My suggestion is to create a new theme (like mytheme) that is a copy of the theme that you are currently using. Then make all your mods in templates/styles/mytheme to override the defaults. Now when you upgrade, you have a single folder that has all of your template customizations. This is not workable if you allow all of your users to select a theme.
If this is unworkable, you can use timestamps or a diff from the distribution. But these are harder to merge back in.
