[embjopr-dev] platform and server nodes in navtree

[Ian Springer]

It seems that due to the nature of embedded, there will always be a 
single platform and a single server as a child of that platform. So I 
think we should get rid of the JBossAS resource type node, which serves 
no purpose other than to confuse, and have the JBossAS resource node be 
directly under the platform node. This would also get rid of an entire 
near-root level of the tree, making it less complex and easier to 
digest. If we do this, I think we could get rid of 
PlatformResourceTreeNode and use SingletonResourceTypeTreeNode for both 
the platform and server nodes.

Thoughts?
