Tough call on this one. I'm a bit wary of letting plugins install hooks,
because that power could be abused.

Maybe we could allow variables to be used by plugin.xml. E.g.:
   <config-file target="res/values/strings" parent="/*"><string
name="my_val">{$PRODUCT_NAME}</string></config-file>
and in config.xml:
   <preference name="PRODUCT_NAME" value="foo" />

That said, I don't think it's that bad to tell users to edit their
strings.xml file.
