Comparing action name

[hungpvdev]

Thanks for create this extension. It 's useful and help me save time in customer request. I found an error make me can't load google script using "Use Custom Action Name".
This value should be trim() before compare with FullActionName.

Please update app/code/community/LUKA/GoogleAdWords/Model/Conversion.php
line 42
$match = ($this->getAction() == $actionName);
-> $match = (trim($this->getAction()) == $actionName);
