Add DialogContextHelper with static accessors to eliminate need to manipulate scoped attributes
directly
--------------------------------------------------------------------------------------------------------

                 Key: SHALE-397
                 URL: https://issues.apache.org/struts/browse/SHALE-397
             Project: Shale
          Issue Type: Improvement
    Affects Versions: 1.0.4, 1.1.0-SNAPSHOT
            Reporter: Craig McClanahan
         Assigned To: Craig McClanahan
             Fix For: 1.1.0-SNAPSHOT


The current implementation of the dialog machinery in Shale occasionally requires the application
to directly access scoped attributes via a symbolic constant string.  Examples include accessing
the current DialogContextManager instance, creating it if necessary.  This is unnecessarily
brittle, and restricts possible future improvements in the actual functionality.

To replace this, create a DialogContextHelper class with static convenience methods that perform
the same logic currently required of the application in these use cases, but abstracted away
to simplify application logic and insulate it from future changes in the internal implementation.
