[Bug Fix] Config "replace" is failing to replace the $root variable

[thinksaydo]

When running the script, the config replace value is failing to replace the $root variable value.

Line 111 has:
if(in_array($root, $replace)){

Should be:
if(array_key_exists($root, $replace)){

Oops, off course. Pushed a fix, thanks!

Thanks Barry! Love what you've done with this package.
