organization and logging

moved config into its own package. config now loads before anything
(including util).

added logging function (wlog) which functions a lot like syslog (now
exporting log levels from config which are named exactly like lispy
versions of their c counterpart). for now wlog just does a (format t
...) instead of doing antyhing fancy. feel free to pipe ;].

added *log-level* to config. (default: +log-warning+)

implemented logging (mainly +log-debug+ and +log-notice+ around the core
wookie systems. working well (very verbose!!)
