Cannot mark asset folders in plugin to always be cooked

No way to mark asset folders in plugin to always be cooked. Using the browse-for-folder button will reject them for not being in the project's content folder. It looks like the code assumes them to be in that folder too, so doesn't look like adding a full path to the .ini file would work either.

1. Add a plugin that contains content files to a project
2. In Project Settings > Packaging, add a new entry to "Additional Asset Directories to Cook", and click the browse-for-folder button (...) next to it
3. Try to add one of the content folders from the plugin
4. Notice that the directory is rejected because it's not under the project's content directory
