#2 StatViz only parses one directive in each config section

[Björn Wiberg]

StatViz only parses one directive (the first one) in
each [Section] in config files specified by --config.

Fix for function loadConfFile():

// go through each directive
// for ($dirI = 0; $dirI <
$section->getChild($dirI); $dirI++) {
for ($dirI = 0; $dirI <
$section->countChildren(); $dirI++) {

Notice the commented-out (original) line, and the
replacement one.

Best regards,
Björn
