SNMP error in device page bug w/fix

[rmcclain]

Many of my devices were showing 'SNMP error' at the top of the device page. I tracked it down, and found that it was having problems with the sysDescr when it's multiline.
To get around this, edit lib/snmp.conf and modify the lines that call

$snmp_value = exec(read_config_option("path_snmpget") . etc...)

inside the cacti_get_snmp function. Make them read instead..

exec(read_config_option("path_snmpget") . etc, $output_value);
$snmp_value = join(" ", $output_value);

This fix has been incorporated into the CVS tree.
