OPENDJ-569 - Fix extensions build.xml to work with NetBeans. Tested with NetBeans 7.2.

First delivery of the OpenIDM password synchronization plugin. The plugin does capture password change and password reset events and currently print them on stdout. Do not use or deploy in production as is. The plugin will be extended to send those passwords to OpenIDM. Building this plugin requires a recent version of ant. Note that there is a bug with MacOS X ant version delivered (1.8.1) which prevents from building the plugin. The fix to ant is in the trunk and will be available in 1.8.2. Building ant from the trunk is a tested workaround.

Fix experimental/build.xml to work with xalan and match the top build.xml file. This now allow to build the example-plugin with the following sequence: "cd experimental, unzip example-plugin.zip, cd example-plugin/, ant"

Move extensions to experimental
