netui-core module

[Rich Feit]

Hi all,

I'd like to split out org.apache.beehive.netui.core.* into a separate 
module: "netui-core".  This will allow the following string of dependencies:
   netui-core -> scoping -> util
Currently, the order is:
   util -> scoping

Which, in addition to being weird, is limiting for scoping because it 
can't use any of the basic util classes like Logger, the 
concurrent-read-map class, etc.  Let me know if you have any other 
thoughts about this.
