Add automodsumm_included_members option

[lukelbd]

Implements item 2 from #91. This adds and documents the automodsumm_included_members option, which is used to add private methods other than __init__ and __call__ to the online documentation. This is useful when creating array-like or dict-like classes, for which it would be useful to document special class methods like __setitem__ and __getitem__.

Looks good, could you rebase this, and add a test? Thanks!

This looks great! fe6154e shows how this feature could be tested.

This was opened from an org's fork to which maintainers can't push updates. Given the inactivity for the rebase and add test comment above, I'll go ahead and open a separate PR with 1) rebasing the commit from here, 2) cherry-pick and fixup the test from the commit mentioned in the comment above.
