Previously the context.xml files are deployed into META-INF folders
in each webapps. They now have been moved into <instance>/conf/
Catalina/localhost/<subsystem>.xml to allow further clean-up.

Previously the config path had to be defined in web.xml, so the web.xml
had to be customized during deployment. The CMSStartServlet code now
has been modified to generate the config path from catalina.base and
webapp's context path by default.

* Added RESTful servlet to add/remove a KRA connector from the CA.
* Modified ACL to allow KRA subsystem user to remove connector.
* Modified connector code to allow the connector to be replaced without a server restart.
* Added functionality to pki CLI to add/remove connector
* Added code to pkidestroy to remove the connector (using both pki CLI and sslget)
  When the issues with pki connection are resolved, we will use that method instead.
* Modified sslget to accept HTTP return codes != 200.  In this case, we were returning
  204 - which is perfectly legitimate.

Trac Ticket #466

The messages in ProfileList.template in CA EE has been extracted
into a properties file which can be translated separately.

The original messages in the template have been marked as follows:
  <span class="message" name="...key...">...message...</span>

When the page is loaded into the browser, the original message will
be replaced with the translated messages.

Ticket #406

All remaining theme files for Tomcat subsystems which include
the templates and JS files have been moved from the theme folder
at <subsystem>-ui/shared/webapps/<subsystem> into the subsystem
webapp folder at base/<subsystem>/shared/webapps/<subsystem>.

The deployment tools have been updated to use the new location.

Ticket #407

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This code has been replaced by ACLInterceptor which will intercept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.
