bandwidthd-php: PHP files to graph bandwidthd data in a postgresql

database
Signed-off-by: Jean-Michel Lacroix <lacroix@lepine-lacroix.info>
bandwidthd-php is a set of PHP files that allows to graph bandwidthd
data stored in a postgresql database.  This bandwidthd data can be
generated using bandwidthd-pgsql in OpenWRT or LEDE or with
bandwidthd on different OS (Windows, Linux for example).

Addition of a config file and an init file.
Modification of the Makefile to take in account the changes above
