Subject: [PATCH] Add getter and setter for error messages

Get the error message:

$image = new Zebra_Image();
echo $image->getErrorMessage(); //This will return a string

------------------------------------------------------------------------------------------------------------
Set custom error messages:

$image = new Zebre_Image();
$image->setErrorMessages(array(
     'Custom message for error n1 - source file could not be found!',
     'Source file is not readable! ',
     'Could not write target file!',
     'Unsupported source file format!',
     'Unsupported target file format!',
     'GD library version does not support target file format!',
     'GD library is not installed!'
));
echo $image->getErrorMessage(); //This will return a string

This makes the code more clean and maybe can be useful (;
Thanks
