Add custom lib to collection of libs to delete from war

If I want to add my own lib to the default list of those to delete because provided by JBoss, I have to redefine the whole list this way :

grails.plugin.jbossas.deleteJarPatterns = ['my-provided-lib*', 'log4j*', 'slf4j*', 'jcl-over-slf4j*', 'jul-to-slf4j*']

I would like to be able to write

grails.plugin.jbossas.deleteJarPatterns.addAll ['my-provided-lib*', 'my-other-provided-lib*']

This does not work because grails.plugin.jbossas.deleteJarPatterns has no default value. If it is not possible to define a default, it could be done by adding another config property.

I also wanted to point out that the doc mention the default value to be ['log4j', 'slf4j', 'jcl-over-slf4j', 'jul-to-slf4j'] while the fallback value in the code contains wildcards.

Thanks for your great plugin!
