Attach method postname

[Crofly]

In the attach method the postname in curl_file_create is not set. This can make problems with APIs which uses this parameter. For Example in an API which i have to call the file i send will have the full Path as name because the postname isnt set.

An easy fix for this would be changing this:

if (function_exists('curl_file_create')) {
    $this->payload[$key] = curl_file_create($file, $mimeType);
} 

To this:

if (function_exists('curl_file_create')) {
    $this->payload[$key] = curl_file_create($file, $mimeType, basename($file));
}

There is also a security problem. The file with the absolute path is always transferred! This can be a information disclosure on file post for the server. We fixed this and started a pull request #278
