Add hook for settings different possible paths

Just a small suggestion,

Possible paths for imagick are define on line 513:

$possible_paths = array("/usr/bin", "/usr/local/bin");

But on my MAMP installation, the path was elsewhere (/Applications/MAMP/Library/bin/).
So it would be great to be able to filter these possible paths, by adding something like this:

$possible_paths = apply_filters("ime_possible_paths", array("/usr/bin", "/usr/local/bin"));

Thanks!
