Resolve type hints automatically and stuff

[ikitommi]

• :hint is resolved automatically, based on a multimethod spec-tools.types/resolve-type (fixes automatically resolve type-hints from core predicates #25)
• :hintvalues are now unqualified. KISS.
• spec has now simpler syntax, :hint is just a extra props (fixes Define a contract for spec-tools/spec and schema-tools/schema #23)
• typed-spec for concise specs with types: (st/typed-spec :long #(> % 10))
• all core-predicates have now a Spec (fixes Support all clojure.core predicates for Dynamic coercion #1)
• spec-tools.convert is now spec-tools.conform. first arg is the spec-record, not the pred
• :hint => :type. It's real.
• key-sets are extracted from keys specs on creation
  • spec-tools.convert/map->strip-extra-keys to strip extra keys away.

(defn map->strip-extra-keys [{:keys [keys pred]} x]
  (if (map? x)
    (s/conform pred (select-keys x keys))
    x))
