Yes, I think that might be a good idea as there is quite a bit of
special casing. We should be adding support for Plasma/Containment
scripting plasmoids in all the queries too, and if all Containments
were always Plasma/Applets too we wouldn't need to do that. There is
also special casing in plasmapkg for Popups and Containments to work
round the problem with them not being Plasm/Applet service types. I
haven't added special casing for Containments in all the places were
applets are listed yet. I wasn't quite sure if they were something the
end user should see, or whether they were going to be some kind of
'internal' system programming feature.

I don't think all the special casing is a great problem if the
Plasma::Applet scripting family is going to stay as it is for the
forseeable future with just Popups and Containments. But if we were to
start having more of them I think it would be right to always make
sure they are Plasm/Applet service types. As it stands I don't mind
much one way or another - it is a bit messy, but not that messy.

While I think about it the project type selector in Plasmate is
different from how the KDevelop or KAppTemplate ones work. In those
you decide what language you want to use, and then under each language
you have a heirarchy of projects types. With Plasmate, you have a
selection of project types, and they under those you have options for
the various languages. Until recently that hasn't made much
difference, but I think the more types of scripting applets we have
the more confusing it will be not to have programming language at the
top of the selection heirarchy.
