Fix evalCond in HTML/DOM renderers: handle scheme-style cond clauses

Browse Source 
The platform evalCond helper (used by render-to-html and render-to-dom)
only handled clojure-style (test body test body ...) but components use
scheme-style ((test body) (test body) ...). This caused "Not callable:
true" errors when rendering cond with nested clause pairs, breaking the
test dashboard and any page using scheme-style cond.
