* Changed the storage location of the consumer key and consumer secret
IDs. This means you will have to run the /msg Botname TWITTER SETKEY
<consumer key> and /msg Botname TWITTER SETSECRET <consumer secret>
commands again to restore the values.
* Moved the "Display the readable name of twitter user" configuration
setting to the user file where it should be, not a global setting for
all users.
* If /msg Botname TWITTER SETKEY or /msg Botnname TWITTER SETSECRET have
nothing after them, they will return in private the two keys that are
stored if any.
