EASOL WIDGET Removal

[edgarf]

We have done some activities to remove EASOL_WIDGET related items from the system. However, one more review is required. We need to check whether EASOL_WIDGET is used anywhere in the system (https://github.com/EASOL/easol/blob/master/application/models/Easol_Widget.php) and if not - let's delete it.

Okay, I've removed the last calls of EASOL_WIDGET and finally removed it.

Great!
