added "conf" function to rapidsms.webui.utils
added "conf" function to rapidsms.webui.utils

this is super handy for altering behavior based on the combined rapidsms
and django settings, without importing os.environ and Config all over.

i also patched the query log to use the new method, as an example of its
usage. to add more debug info to the webui, check out the templates and
apps.webui.templatetags.debug.debug_dump() -- visibility can be toggled
using the [django] debug=true setting
