refactor(jqLite): remove jqLite show/hide support

it turns out that even with our tricks, jqLite#show is not usable in
practice and definitely not on par with jQuery. so rather than
introducing half-baked apis which introduce issues, I'm removing them.

I also removed show/hide uses from docs, since they are not needed.

Breaks jqLite.hide/jqLite.show which are no longer available.
