Dynamically calculate asset size and store as a build configuration

[benwicks]

I may want to update the (JSON, XML, or protobuf) files in my assets directory. When they change, I would like to re-calculate their size on disk and store the value as a string resource or a value in the build.config file so I can "hard-code" the values into the app and show the user the size of the assets on the DataFormatsListView. I am currently storing these values as Strings in DataFormat.
