Improving the IdP's startup time on tomcat

[Tom Zeller]

We try to keep catalina.properties up-to-date in the example
tomcat-base that we test with.

Right now it skips JARs from the IdP and OP Plugin JARs, but no other
IdP Plugin JARs at the moment.

Some documentation here :

> I have not tried to disable TLD scanning. This looks like it could save another 3 seconds but looks like it would complicate upgrades due to the need to track jars.
