[Developers] Parameter sharing and inheritance

Ian Hinder had a problem with parameter sharing in Cactus.  Thorns  
were activated in the wrong sequence, but Cactus did not catch the  
problem.  In particular, he had a thorn which shared a parameter from  
MoL.  This thorn did not inherit from MoL.  The thorn was  
nevertheless activated before MoL.

There seem to be two ways to solve this problem.  One, we could make  
it illegal to share parameters without inheriting.  Two, we could  
take parameter sharing into account when calculating inter-thorn  
dependencies.  (This has nothing to do with the link list, but there  
still is a dependency when activating thorns.)
