Rename module to be called "purifier" so that we can create a purifier

helper which in turn calls HTMLPurifier.  This makes a cleaner
inter-module API.  The module has to be renamed to avoid having two
classes called "HTMLPurifier"

Also clean up the module.info and move the config settings over from
modules/gallery.
