Need to expose the filter list for the default Filter implementation on URLDeploymentScanner

Adding new patterns of files that the URLDeploymentScanner should ignore currently requires a custom class implementation. The default Filter attribute:

<!-- The Filter specifies a java.io.FileFilter for scanned
directories. Any file not accepted by this filter will not be
deployed. The org.jboss.deployment.scanner.DeploymentFilter
rejects the following patterns:
"#", "%", ",", ".", "_$", "#", "$", "%", "*.BAK",
".old", ".orig", ".rej", ".bak", ",v", "~", ".make.state",
".nse_depinfo", "CVS", "CVS.admin", "RCS", "RCSLOG", "SCCS",
"TAGS", "core", "tags"
-->
<attribute name="Filter">org.jboss.deployment.scanner.DeploymentFilter</attribute>

cannot have prefixes and suffixes added without creating a custom filter implementation. There should be basic support for configuring the DeploymentFilter using either the javaBean support:

<mbean code="org.jboss.test.jmx.complexattrs.ComplexAttrTests"
name="test:name=ComplexAttrTests,case=#1">
<attribute name="Bean2"
attributeClass="org.jboss.test.jmx.complexattrs.JavaBean2"
serialDataType="javaBean">
<property name="i">12345678</property>
<property name="f">1.23456</property>
<property name="d">3.14159265358979323846</property>
<property name="l">1234567890</property>
</attribute>
</mbean>

or, the under development jbossxb mechanism:

<!-- Tell JBossXB about the namespace to factory mappings in this doc -->
<?jbossxb ns="urn:schema:ns1:jbossxb"
factory="org.jboss.test.jmx.complexattrs.JavaBeanObjectModelFactory"?>
...
<!-- Test the jbossxb attribute data type syntax -->
<mbean code="org.jboss.test.jmx.complexattrs.ComplexAttrTests"
name="test:name=ComplexAttrTests,case=#2">
<attribute name="Bean1"
attributeClass="org.jboss.test.jmx.complexattrs.JavaBean1"
serialDataType="jbossxb"
xmlns:ns1="urn:schema:ns1:jbossxb">
<ns1:javabean1>
<property name="bindAddress">127.0.0.1</property>
<property name="someDate">Sun Jan 2 23:26:49 PST 2005</property>
<property name="props">

prop2=value2
prop3=${prop3.systemProperty}
</property>
<property name="names">name1,name2,name3</property>

</attribute>
