Upgrading Widgets from plasma-workspace

Hello,

I'm working on a temporary solution to the problem - I implement 
filtering by device name (sd*, sr*, vd*,..). This should work until 
another solution is found.

Sometimes the user may try to disable the last checkbox and all 
checkboxes will turn on immediately in the settings.
It may be inconvenient for users to uncheck a large number of checkboxes.

There are two possible solutions:
1) Not allow to uncheck the last checkbox. There will always be at least 
one graph.
2) Allow to uncheck the last checkbox. In this case, the widget will be 
empty.

Now I have implemented the first option - I have forbidden to disable 
the last enabled checkbox.
