CAS-1251: Move the JsonExceptionView resolver to the management webapp module, make sure only ajax exceptions are handled by the resolver. Fixed a bug with the management webapp's prefix and cleaned up the poms.

Ported Scott's HtmlEscapedExceptionMessageExceptionHandler.
CAS-1248: CASImpl ignores authentication attributes when registered service is set to ignore attribute release policy of svc registry
CAS-1207 Make cglib a direct dependency of cas-server-webapp.

Both cas-server-webapp and cas-server-integration-restlet depend on cglib; the former via transitive dependency on spring-json and the latter directly. Placing the dependency directly in the webapp artifact and removing it from the other locations cleans up the dependency graph when both webapp and restlet are used together. It's safe to remove the dependency from restlet since there is no use case for using it without webapp.
CAS-1207 Add maven enforcer rule to prevent banned cglib artifacts.
CAS-1248: Cleaned up the way attributes were collected into the hashmap.
CAS-1251: Move the JsonExceptionView resolver to the management webapp

Addressed issues raised by Scott. Fixed the import location, used a direct "return null" instead of a stale variable and removed the message key constant.
Merge branch 'master' into CAS-1251

CAS-1253 Avoid duplicate joda-time dependencies.

Duplicate joda-time dependencies may arise in overlays that include cas-server-support-ldap. Declare direct depencency on joda-time for core and cas-server-support-ldap and exclude from transitive dependencies to ensure single consistent version.

CAS-1251: Move the JsonExceptionView resolver to the management webapp

Fixed exclusions tag issue with pom that had made its way into the commit via a malformed merge with master.
Added an empty line after the import statements in ajax exc resolver class.
CAS-1238 New AH interface for LPPE generalization and clear error handling.

A new AuthenticationHandler component in the root authentication package
provides a number of notable features consistent with long-term goals:

1. Provides rich metadata (HandlerResult) on success that may be used by
   higher level components. For example, a JDBC AH might express a password
   expiration condition by setting getWarnings() that may be leveraged
   by LPPE components.
2. Clarifies error handling contract to distinguish between an
   authentication failure (GeneralSecurityException) and a situation
   where authentication was prevented (PreventedException). The rich
   vocabulary of the GeneralSecurityException hierarchy allows a natural
   mapping from common failure modes (e.g. password expiration) onto
   concrete exception classes.
3. Package structure allows both old and new AH components to coexist,
   providing a transition path for existing CAS adopters to gradually
   migrate custom authentication handlers to the new API.
   The LegacyAuthenticationHandlerAdapter component provides an out-of-box
   transition strategy.

CAS-1259 Report ERROR status when Monitor throws unchecked exception.
CAS-1251: Possible Cross-Site Scripting on /login using execution parameter

Follow-up work on the previous commit around CAS-1251, this commit generalizes NoSuchFlowExecutionExceptionResolver to handle FlowExecutionRepositoryException is a common ancestor to webflow exceptions. Hiding these exceptions, such as BadlyFormattedFlowExecutionKeyException, would allow us to present the error page to the user as opposed to having the error rendered directly on the page which may include JS code passed to the /login CAS URI.

The HTMLEscaped handler is now removed, since it was originally intended for the webapp and not the management webapp.
