Easy Google Analytics vs google_conversion_currency

Hi,
adwords experts were complainig about the code created by Easy Google Analytics.
They said that is has to be exactly like the one you can get from their site or they could not give assistance about crazy reports I get from adwords.
So I ventured in a mod to the file google_analytics.php included in the folder \includes\templates\your_template\google_analytics of the original file set of the plugin Easy Google Analytics by Numinix.
The code I came out with is

It seems to work nicely and give a cleaner snippet.
The only thing that is needed to do (and I am not able to to do it modding the installer of the plugin) is to create manually the field GOOGLE_CONVERSION_CURRENCY in the configuration table of the data base.
Once done that in the admin page under the configuration of Easy Google Analytics it will be needed to input the three digits of the currency of your site. May be that is is also needed to create a multiple currency system but that goes way beyond my programming capability.
