WAFFLE_SWITCH_MODEL is missing from the "Configuring Waffle" docs page

[allanlewis]

The setting WAFFLE_SWITCH_MODEL allows using a custom switch model. It's documented on the Switches page but not on the Configuring Waffle page. For comparison, the equivalent setting for flags, WAFFLE_FLAG_MODEL, is documented on both the Flags and Configuring Waffle pages.

Perhaps there are other settings missing from the Configuring Waffle page? I haven't checked.

Feel free to submit a pull request with a fix.

If someone can supply a description of WAFFLE_SWITCH_MODEL for the docs I'd be happy to raise a PR; I'm not sure how to describe it myself.
