Push version to circe-1.1, tracking-1.2, lui-1.1
build.sh: Use correct versions for packages that don't change.

This used to use "lcs-1.1" as the version instead of "1.1".
circe-fool-face: not bold in X

In situations where this face is together with other faces in a single
message, text color may come from another face (depending on precedence),
but the bold attribute contributed by circe-fool-face then serves to
emphasize the message, counter to the intent of the 'fool' system.  This
change only affects X; the bold attribute is kept for tty, where styling
choices are more limited.
circe-server-message: Don't add the server face here.

This is done by circe-display for server messages. Doing it here
will make it show up twice.
circe-lurker-p: Handle the case where circe-active-users-timeout is nil

If there is no timeout, the user is not a lurker.
circe-color-nicks.el: Handle "unspecified-bg" and "unspecified-fg".
