Fixed a very slight security problem with bib-remote. Communication with bib-remote is based on signal USR1, which you can only give the process if you are the user or superuser. So, that part seems secure. Then communication proceeds through a file, and now bib-remote checks that the file doesn't exist beforehand, and it is created with umask 077. Handles Unicode characters.
Entry can be either as tex, or as unicode.
Old bref files will load correctly, and be displayed correctly. New bref files are stored with unicode in them. New interface with emacs. Sixpack can insert citations into emacs using gnuclient. This can be invoked with alt-m.
