SettingsStore::open read XDG_CONFIG_HOME and HOME itself. Neither
exists on Android, so it resolved to .config/darkroom relative to a
working directory of /, and every settings edit on the tablet failed
with "read-only file system" — the page reported the error and nothing
said why. The doc comment claimed "the same resolution SessionStore
does"; now it is, by calling the same function, which honours the
directory android_main declares and takes the platform's config
directory everywhere else. settings.json sits beside sessions.json on
every platform, as the comment always said it did.
