[e-lang] Guard-based auditing now implemented in E-on-CL

[Kevin Reid]

E-on-Common-Lisp now provides (and uses) the experimental 'guard- 
based auditing' feature.

Guard-based auditing replaces the (insufficiently powerful)  
unshadowable-names/synEnv system currently provided by E-on-Java, and  
the (POLA violating) getGuard/1 previously provided by E-on-CL.

See http://wiki.erights.org/wiki/Guard-based_auditing for more  
information about how it works.

If you're interested, please try it out and/or review the wiki design  
issue page.
