Added double quote for whitelist in functions.inc.php

[ConiKost]

Could we add double quote for the whitelist in functions.inc.php?

If it's not added, some images for the GenericJMX plugin will fail due their naming. Works for me, but I don't know, if it has impact on other things?

PHP message: Invalid plugin instance in $_GET["pi"]: "request_processor-"https-openssl-apr-8443""" while reading response header from upstream

The problem are those directories with double quotes in their names: drwxr-xr-x 2 collectd collectd 4096 18. Jul 22:55 'GenericJMX-request_processor-"ajp-nio-8009"' drwxr-xr-x 2 collectd collectd 4096 18. Jul 22:55 'GenericJMX-request_processor-"http-nio-8080"' drwxr-xr-x 2 collectd collectd 4096 18. Jul 22:55 'GenericJMX-request_processor-"https-openssl-apr-8443"'
