add a option to exclude classpath entry.

Let user have a chance to use regex to exclude some jar/classpath folder when 
launching.

Ready since 2011/7/6
committed r212 , also bootstrap in r207.

Note that if entry is excluded, you will get notification in console.

and the excluded classpath text MUST BE a valid REGULAR EXPRESSION , 
we will use it to match all entry one by one when we add it to classpath list.

If user typing a invalid regex string , we will show up warning and ignore this 
config then.

How do you use this feature?

I set -Drjrexcludedclasspath=".*" in my Run Configuration's Arguments section, 
and it does nothing.

When I set that property to an invalid regular expression, I do get an error 
from RunJettyRun saying it's invalid, so it is detecting and using the property.

Why would the ".*" regular expression not exclude every classpath?

The latest version of ProjectClassLoader.java doesn't use regular expression 
matching anymore, it just searches for strings that start with "-n-" and "-y-", 
but the error message in "bootstrap/src/runjettyrun/Configs.java" is still 
there.

How do you exclude paths from the classpath now?
