Since all paths to the theme images and CSS files have been
updated, it's no longer necessary to copy these files into
subsystem's web application. The deployment tool will still
need copy the Velocity templates.

Ticket #328

Currently the theme files are copied into each subsystem during
deployment creating duplicates. To reduce the problem the files
should be combined into a common folder /pki.

The process will be done over several patches. Initially this patch
will copy the images and CSS files into /pki/images and /pki/css.
Subsequent patches will update references to these files to the new
location. When it's done, the files no longer need to be copied
into each subsystem.

Ticket #328

Previously ACL checking was done in PKIRealm by matching the URL.
This code has been replaced by ACLInterceptor which will intercept
RESTEasy method invocations. This allows more precise mapping of
REST methods to ACL entries in acl.ldif.

Ticket #287

The CertPrettyPrint has been modified to use the standard names
for message digests so that it will work with standard security
provider.

Ticket #392

The wrappers for PrettyPrintCert and PrettyPrintCrl has been fixed
to include the class names.
