Support link units with 5 links

Google adsense link units are available in both 5 link format and 4 link format. Code for 5 link format is '_0ads_al_s' .

For those who are impatient for the next release
replace

‘180×90′ => array(’type’ => ADSENSE_TYPE_LINK, ‘desc’ => t(’Ad links 4-links 180×90′), ‘code’ => ‘_0ads_al’),

with

‘180×90′ => array(’type’ => ADSENSE_TYPE_LINK, ‘desc’ => t(’Ad links 5-links 180×90′), ‘code’ => ‘_0ads_al_s’),

I got the code for 5 link units from

You have to manually clear the cache if caching is enabled. I delete all the entries in cache table and it worked. Thug it sounded easy at first, it is a bit of hassle to get the code, change the script and clear the cache.

This hack is working well for me. You can see it in action here at our free press release site.
