/**
* The plugin manager handles the application plugins. The mainwindow form
* has an empty dedicated QVBoxLayout that can be used from plugins to show
* them selves in the main form. If a plugin requires a lot of space then
* you can use a dedicated window and only add a very small ui element that
* spawns that dialog. Finaly, the element from the mainwindow that is also
* used from the plugin manager is the the 'Plugins' dropbox menu item. Every
* plugin has an action on that menu and every time that the action then a
* new plugin object will be added; therefore, try to write plugins in a way
* that multiple instances can be loaded!
*
* The pluging manager provides plugins with the finctionality to be able to
* change the content of the serial cmd string before it's send on the serial
* port by using the function `processCmd()`. Because there can be several
* plugins that may be able to modify this string, be aware that the priority
* order is the same with the index of the plugin in the plugin QList (m_list).
* Also every pluging can send a serial command with the `sendCmd()` signal.
*
* Make sure that plugins clean up themselves properly when unloaded.
