Title: Programmatically Iterate Resources in a Deployment

Describe the issue:

Several minor changes.

Suggestions for improvement:

1. The correct link for JBoss Modules API docs is "http://docs.jboss.org/jbossmodules/1.3.0.Final/api/".  I was working on getting a more general 1.3 symlink set up but it's not working, so this will have to do for now.

2. "Iterate All Resources Found in a Single Module and Imported Resources" section has a typo in the code sample "Interator" instead of "Iterator".  Probably me, as I make this typo all the time.

3. Some code examples:

* Find all files named "foobar.properties" in my deployment

ModuleClassLoader moduleClassLoader = (ModuleClassLoader) TargetClass.class.getClassLoader();
Iterator<Resource> mclResources = PathFilters.filtered(PathFilters.match("**/foobar.properties"), moduleClassLoader.iterateResources("", true));

* Find all files name "foobar.properties" in my deployment and imports

ModuleClassLoader moduleClassLoader = (ModuleClassLoader) TargetClass.class.getClassLoader();
Module module = moduleClassLoader.getModule();
Iterator<Resource> moduleResources = module.iterateResources(PathFilters.match("**/foobar.properties));

* Find all files inside any directory named "my-resources" in my deployment

ModuleClassLoader moduleClassLoader = (ModuleClassLoader) TargetClass.class.getClassLoader();
Iterator<Resource> mclResources = PathFilters.filtered(PathFilters.match("**/my-resources/**"), moduleClassLoader.iterateResources("", true));

* Find all files named "foo" or "bar" in my deployment and imports

ModuleClassLoader moduleClassLoader = (ModuleClassLoader) TargetClass.class.getClassLoader();
Module module = moduleClassLoader.getModule();
Iterator<Resource> moduleResources = module.iterateResources(PathFilters.any(PathFilters.match("**/foo"), PathFilters.match("**/bar"));

* Find all files in a specific package in my deployment

ModuleClassLoader moduleClassLoader = (ModuleClassLoader) TargetClass.class.getClassLoader();
Iterator<Resource> mclResources = moduleClassLoader.iterateResources("path/form/of/packagename", false);
