Extension Manager misses a way for 3rd-party extensions to process available actions.

This could be used, e.g., by EXT:documentation to open the corresponding manual by redirection to the documentation module and opening it (it's up to the extension to choose what to do). Another example would be for extdeveval (or any dev-oriented extension) to add an icon to "manage" the extension from a developer point of view.

It's not up to the EM to provide all those features but it should let other extensions add them as EM acts as a central hub for managing extensions (whatever it means according to the various points of view).
