Reverted indentation level to 3.

 Changed default indentation level to 8, to make it presbyopia-friendly

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).

added some vserver documentation to README and to the handlers

rdiff works with sshd banner... rdiff local dest works... create logfile... when=hourly... rdiff nice...
