ns-resolve might throw ClassNotFoundException but should return nil

Description

The doc of ns-resolve states that in case the symbol cannot be resolved, it should return nil.

However if the symbol contains dots and is not a resolvable Class, a ClassNotFoundException is thrown

Approach: Catch CNFE when attempting to resolve a dotted symbol as a class and return nil instead.

Patch: clj-1403-2.patch

Screened by: Alex Miller
The attached patch makes ns-resolve return nil in that case instead of throwing an exception

Updated the patch so that it compiles fine on JDK8

Nicola, the patch 0001-CLJ-1403-ns-resolve-returns-nil-if-class-is-not-foun.patch dated 31 Aug 2014 applies cleanly to latest Clojure master as of Oct 1 2014, but fails to compile with JDK8. I haven't checked whether it compiles cleanly with other JDK versions yet.
