[Building Sakai] CAS and other filter configuration for login tool

[John Bush]

it controls the CAS/shib config.  Its not tied to the
sakai-configuration.xml, because it needs to be loaded at the webapp
lifecycle, you wouldn't be able to do that with that older mechanism
b/c there is no web context to deal with the filters, I'm certain
spring would not like that.  I put a ticket up so people can look at
it, might make more sense with something to look at.

The nice thing is for implementors you can adjust your config and then
recycle the login-tool to apply config changes, no need to restart the
whole tomcat and component mgr.
