Added my email address to AUTHORS file

said error was orange and fatal was red, maybe this is better?

Also fixed a bug in the rdiff handler that caused a unary operation error if
the variable wasn't fixed

added more verbage to ninjahelper
added some IFS=$'' to easydialog
(this allows you to pass through blank lines).

No commit message

 Replaced awful "grep /etc/passwd" with getent calls in pgsql and mysql handlers

and maildir handler for creating safe temp files.
