Previously, we had a silent failure of the dbus call to "reloadConfig"
which turned out to be a signal and not a method that we can call. To
reload effects, we need to manually call dbus to load and unload each
individual one. A similar situation exists for scripts, except that we
only unload scripts through individual calls, and call `start` to load
all of the enabled scripts at once.
Adds an experience for users on first login, allowing some basic configuration.
This is separate from a first start wizard, which would run as a separate user with elevated permissions, and include options that an installer would have.
