Import cacti-0.8.7b as wip/cacti.

Cacti is a complete frontend to rrdtool, it stores all of the necessary
information to create graphs and populates them with data in a MySQL
database. The frontend is completely PHP driven. Along with being able
to maintain Graphs, Data Sources, and Round Robin Archives in a
database, cacti handles the data gathering also. There is also SNMP
support for those used to creating traffic graphs with MRTG.
