distributable tag in _other_ webapp causes cas to except

[Scott Battaglia]

It appears that Tomcat's clustering is based on serializing objects across
the different nodes.  The CASReceipt object is not serializable (i.e. does
not extend Serializable).  The easiest and quickest solution is to modify
the source code of the library to make the CASReceipt serializable.
