Updated readme to reflect the fact that insert, update, delete are

already implemented.

+Inserts are supported:

+```clj
+(-> (insert-into :properties)
+    (columns :a :b :c :d)
+    (values
+     [[1 2 3 4 5]

+```
+
+Updates are possible too (note the double S in `sset` to avoid clashing
+with `clojure.core/set`):
+
+```clj
+(sql/format
+ (-> (update :films)
+     (sset {:kind "dramatic"
+            :watched true})
+     (where [:= :kind "drama"])))
+=> ["UPDATE films SET watched = TRUE, kind = ? WHERE kind = ?" "dramatic" "drama"]
+```
+
+Deletes look as you would expect:
+
+```clj
+(sql/format
+ (-> (delete-from :films)
+     (where [:<> :kind "musical"])))
+=> ["DELETE FROM films WHERE kind <> ?" "musical"]
