Propose: support different levels of logging on wok

Bug: wok is setting logging handlers only, not cherrypy handlers.

Issues:
After my troubleshooting, just saw that we need to set cherrypy handlers:
--- a/src/wok/server.py
+++ b/src/wok/server.py

When testing, got this output:

Running with loglevel == debug
command-line ./src/wokd: No output

access_log: lot of output, info output and commands results

error_log: debug info

------------------------

Running with loglevel == info
command-line ./src/wokd: No output

access_log: lot of output, info output

error_log:  info

--------------------------------

Running with loglevel == error
command-line ./src/wokd: Info output (no expected)

access_log: just calls to the urls

error_log: only error

The last one was not expected :(
