Create a generator for symbols.
Also modify the keyword generator to allow :'s (as per the spec) (http://clojure.org/reader)
Create generators for namespaced symbols and keywords, as these were not tested before.
The new generators are added to gen/any.
A patch (namespaced-symbols-2014-07-11-14-38.diff) is attached.
Also a suggestion (but not in the patch): the edn-roundtrips test should be run separately on each type in gen/any to adequately search the space for errors.
