- Add the new User containers for easier handling of users throughout the codebase
- Remove the swap_player event (replaced by User.swap, made possible thanks to the containers)
- Remove the cli argument from several events
- Remove !frole (a replacement will follow)
- Remove the ALLOWED_NORMAL_MODE_COMMANDS config option
Plus a couple of small fixes here and there.
This gets rid of the (dced) hack, with var.DCED_LOSERS taking its place.
Succubus was not touched, as there is already a PR which converts it,
although the succubus events in other files were touched.
Some sites were updated to be (more) Users-aware, while others replaced
it with an old deprecated get_roles() API. As more things get converted,
these will hopefully get eliminated as well. A FIXME comment was added
to all such occurrences.
