Proposed changes to adtwirl code

[khan]

i have checked adtwirl ads and there are currently only ppc ads running,
for 11 clicks you should have more than 0,04 in earnings, looks like someone clicked the "ad" image link which leads to page with free ads and paid ads,
anyway, now i have removed the link from the "ad" image so its no longer clickable.

there are more adult ads at adtwirl for north america and west europe.

Lets see how it effects on earnings.
