SWS-907 - Become compatible with Spring Security 4

Spring Security 4.0 removed a number of APIs that were deprecated in
3.x. This commit updates SpringSecurityUtils to avoid using those
APIs. This makes it compatible with Spring Security 4.0 while also
retaining compatibility with Spring Security 3.2.x.

Also, upgrade to Spring Security 3.2.7.RELEASE as the latest point release.
