Automaticaly redoing the rrd redo files after creating a new rrd database

Nadoz automaticaly checks the presence of the rrd databases and if they are not present, it creates them. Before it checks the presence of the 'rrd redo' file (a log file with all the rrdtool update command in unix shell format) and checks the datetime of the first log in order to create the databases.
The next step is to redo all the logs (just after creating the database) to populate the base with all the old datas.
