Trunk build 090312.

I have some simple code which allows me to define a project template in a properties file
(relative/path/in/project=sfs/path/to/template).  I am using FreeMarker for templating.

With ergonomics disabled, this works fine.  With ergonomics enabled, project creation fails with the exception below. 
First there is the following warning:

WARNING [org.openide.loaders]: Should override getLookup() in class
org.netbeans.modules.ide.ergonomics.fod.FodDataObjectFactory$Cookies, e.g.:
[MultiDataObject.this.]getCookieSet().getLookup()

Then I get the exception below.

I must hold ProjectManager.mutex() while creating a project on disk.  But if ergonomics is enabled, the code that looks
up the file encoding calls the default DataObject.getLookup() which invokes getNodeDelegate().getLookup() - and acquires
Children.MUTEX, causing the exception.

I must not create the project outside of ProjectManager.mutex(), and I cannot instantiate a template inside
ProjectManager.mutex()... == I cannot create a project.  Probably either having FodDataObjectFactory's DataObjects
properly override getLookup(), or creating some code path to query file encoding would solve the problem.  But I wonder
how many more problems like this there are.
