Cron module updated (as requested by Djkanna)

Hi,

Djkanna requested a nice feature: to be able to run the crons manually from the admin panel, for debug or other reasons. So it's there, if you update the cron module, you will find a new admin menu entry which will let you run the crons when you want.

Neat, thanks for your time and effort.

NP, it's a must to support a product, plus it was not such a huge work ;)
