Big commit

 * Added manpages for all binaries
 * Added log-reopening for mauvealert-server, and logrotate snippet
 * mauveserver now adds a user on install, and runs as that user
 * Big logging tidy-up
 * Alert subjects are only overwritten by the source, when the subject in the databse is empty
 * Removed various attr_writer methods that were being redifined
 * Added a notes box to the acknowledge form, but this doesn't work yet
