trivial code change

 Added some vserver handling to determine correct home directory, also
 enhanced error handling

 Added -q to vserver-info test in mysql handler to quiet the test
 to see if it is running

 Fixed mysql check to see if vserver is running

 Added trac patch to fix subdir mkdir problem

 dup.helper: now remembers the src-section values (includes, etc.) inside one do_new session

 dup.helper: some code cleaning

 pgsql.helper: forbid the user to choose an empty database set to backup

 ninjahelper: moved (and enhanced) vservers-related functions to lib/vservers. dup.helper, pgsql.helper: use these functions

 dup.helper: disabled connection setup, waiting for rdiff.helper code to be shared in some lib.

 Moved more code to lib/ (conffile-related functions, parseini. Added dup helper, using new modular vservers-related functions shared for all helpers.

 Delete handlers/easydialog.sh since it's now in lib/.

 Moved easydialog.sh to lib/ directory: more code is going to be shared, let's start here.

 rdiff.helper: (re)rename do_rdiff_conn function to do_rdiff_ssh_con, since the previous rename was not the good one.

 rdiff.helper: rename do_ssh_con function to do_rdiff_conn, in order not to pollute namespace... and allow future code factorization :)

 easydialog: add optional third argument to booleanBox, to set default no if needed (and actually needed by the upcoming dup.helper).

 Fix formDisplay to reset $REPLY as it should.

 Fix listBegin/listItem/listDisplay to work with checklist boxes, as advertized.

 Fix: the "Cancel" buttons used to have a weird behaviour... at least

 Fix: used to expand '*' in default source directories

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).

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

and maildir handler for creating safe temp files.

(adds ignores option)

mysql helper bugfix: write yes/no to config file instead of on/off, that are not recognized by mysql handler
