zshrc: tweak history

Make use of the HIST_IGNORE_SPACE option to allow for (1) private
sessions where the new 'private' and 'unprivate' aliases are not stored,
and (2) more compact history by disabling history for common aliases
like 'l', 'll', 'k', 'q', etc., and also "one-shot" aliases that never
take arguments, such as 'es', 'ees', 'of', 'ofo', etc.
