As of now, themes and plugins headers (e.g. "Plugin Name:") can be represented in only one language. We need a way to translate those.
I was thinking maybe we could have an info.xml maybe, which could be something like:
<name> <en>Sample plugin</en> <fr>Sample plugin in french</fr> </name>
This is especially important in multisite environments where users have the option to enable plugins or activate themes, but they can't read the details.
The theme and plugin repositories should be multilingual too! :)
