[Release] Clean and Package Orginization plans

[Keith Hodges]

I wanted to make an "easy" way to make tests unloadable and loadable. At 
present we have two conventions in the image, and I want to try and 
simplify.

The first convention is to have categories suffixed "Tests", or "Testing"

e.g. System-Event Notification-Tests

The second is to have categories such as "KernelTests" or "NetworkTests".

I would like to standardize on the first more commonly use convention, 
and make supporting tools available to everyone.

To this end I have updated PackageInfo so that packages called 
Kernel.impl and Kernel.test will save the impementation and the tests 
separately.

The following reorganization is suggested:

Having made this reorganization tests can be removed using

Installer unload: '*.tests'.

comments requested.
