With this patch interfaces with mac_filter option are at least displayed
on the GUI. But it is still not possible to set the option, because
vzctl netif_add does not support the option.

New create_rrd_graph returns image data directly - no need to read from file.

Comment from Stefan: I've seen that it takes up to 10 cycles to have a
constant memory size. I think this is due to the fact that perls garbage
collection is not running every after each cycle.

Previos code creates the directory on the wrong node!
