Adaptation of add-ons Joomla 2.x for Joomla 3.x

There are 4 add-on (based on the same code base with minor modifications) and 1 extremely similar.

The plugins run on Joomla 2.x but on 3.x do not start. You may need to edit the XML manifest, and it is possible to slightly tweak the code.

In General, it is necessary to make so that they can be set as 2.x and Joomla 3.x.
