Document -tagged, -not -tagged, and -not -starred

[micahellison]

Fixes #1668. Documents the behavior modified in #1663.

In the long run, I think we'll want a more polymorphic approach to documenting -not, but since it only supports three different inputs and two of them are already search arguments, I thought it best to keep it all separate for now. This also helps with the table layout on the site, since it can't be widened nicely in our current docs style.

Turns out this was already done in the original PR, and looks pretty good to me:

  -not [TAG/FLAG]       If passed a string, will exclude entries with that tag.
                        Can be also used before -starred or -tagged flags, to
                        exclude starred or tagged entries respectively.
