Fixed yell message in transportlayer

Now yell message should work as intented in transportlayer (BFRCON)
Plugin structure change

Changed how plugins are being structed.
Now instead each plugin will be placed in a separate folder. This should
make it easier to new users on were each plugin is located.

also changed the name of pluginbase class to make it even more clear
Changed the plugin folder name

This is to make it simplier in the future. Each battlefield game will
have it's own pluginbase as well as plugin folder
Updated paths and regret my choice on renaming pluginbase

New structure now works as it should
