Downloaded modules lack input mappings (module scanning)

[Cervator]

If you download a module in-game, possibly specifically as part of connecting to a server, you skip the regular process that parses out hot key configuration. As a result if you connect to a server running JoshariasSurvival while having deleted all modules locally you can't access anything like inventory, the help system, the skill screen, etc.

While that might lead into a bigger topic of how to handle input bindings for modules (where conflicts can happen more easily) I imagine we can trigger some sort of module rescanning process after having retrieved new modules, so we can update the default input mappings. I'm unsure if this might help other stuff too, that may relate to updating stuff after a change in modules.

In the meantime simply restarting the game lets it work since at that point you get all the keys configured as part of regular initialization.
