[security-dev] IDM: Support for XML configuration

I've started the work on XML based IDM configuration and sent first PR 
related to this https://github.com/picketlink/picketlink/pull/38

What I did so far is:
1) Created Java classes for types which are used to XML-Java mapping. 
For now, I added those classes into "picketlink/federation" module into 
package "org.picketlink.identity.federation.core.config.idm" .

Only reason to have them in federation is, that they need to be visible 
from class PicketlinkType, which is part of Federation module. (It was 
agreed that we will use big picketlink.xml, which will contain 
configuration of all picketlink components together). Seems that we need 
to extract some stuff related to XML parsing from federation module into 
config module, as currently "config" module is dependent on "federation" .

2) I've made STAX based XML parsing in config module. See 
IDMConfigParser and unit test IDMConfigParserTestCase

3) I've added some temporary reflection based hack to 
PicketlinkConfigParser, so it can instantiate IDMConfigParser from 
"config" module and use it. This needs to be done more properly once/if 
we extract XML parsing stuff from "federation" module to "config" module 
(mentioned in point 1)

4) I've added class XMLBasedIdentityManagerProvider to IDM. It will be 
used to build IDM IdentityManager from parsed XML configuration. Not 
much work done here atm. I am planning to  use reflection based classes 
from IDM module to help with this.

Let me know if there are some questions/concerns around this.
