network command with no user
ignore blank lines from both servers and clients
version 0.8.10
Allow admins to create networks regardless of settings

Previously admins could only create networks if they first
set the 'allow_user_networks' setting to true. They should
be able to create networks without modifying that setting
since they are admin, not users. However, non-admin users
should still not be able to create networks unless that
setting is set to true.
Match the Setting help to a valid setting.

Previously the help example for setting was

SETTING public_registration true.

However, the setting key tkellem is looking for
is user_registration, checking that it's not 'closed'
So a more helpful example would be:

SETTING user_registration open
Add some information on device-based backlogs

This information was lacking in the Readme, making it
hard for new users of tkellem to take advantage of
per-device backlogs.

Check if tkellem is running first on tkellem start

Make sure tkellem isn't already running when the user types
tkellem start. If it is running already, print out a relevent
message and exit instead of daemonizing another instance.

Fixes #31
Rename running? to abort_if_running

Follow ruby naming convention. This method originally
returned a boolean, but I changed what the method did
and forgot to rename the method appropriately.
