filesets-add-buffer

["Chong Yidong" <cyd@stupidchicken.com>]

Currently, the command filesets-add-buffer forces the user to supply the
name of an existing fileset.  With this patch, if the user supplies a new
name, a new fileset is created.  I think it is good to do this, because
currently there isn't any quick and easy method to create filesets -- you
have to do M-x filesets-edit and wade through the very confusing and
difficult-to-use Customize buffer for filesets-data.
