Centralized catalog for supported plugins.

[Stvad]

It would be nice to have some catalog of plugins that you can install via AnkiHub. In the simplest version, it could be a file in some central repo with links to other repos with plugins. And those repos should have some file that will provide some metadata about the plugin. So in the end, you would be able to browse and install them from within AnkiHub (like in Linux package managers or various IDE's plugin managers)
