update wizhelp for ^O and #wizwhere

I think ^O changed when the dynamic key-binding code was incorporated.
It's a shortcut for #overview in all modes.  To get the old wizard mode
behavior, use #wizwhere.

Add an entry for #terrain, expand several of the descriptions, and fix
up the formatting (remove periods in ^ section, align text in # section).
