Summary: 'ns_env unset' removes value, not key

Initial Comment:
 
As seen in command line mode: 
 
% 
% ns_env set LALALA 123 
% ns_env exists LALALA 
1 
% ns_env get LALALA 
123 
% 
% ns_env unset LALALA 
% ns_env get LALALA 
% ns_env exists LALALA 
1 
% 
 
This is contrary to the usual use of variables (and arrays) where 
an 'unset' command will remove the variable (not only value) 
and 'exists' will return 0.
