As there is a collection-texworks with one package and one collection, i 
thought it could be an idea to put the 43 datetime2-packages also in a 
collection. The collection-latexextra would look a little more clear, as 
it would have contained the the new collection instead of the single

At least some packages have set some dependencies, e.g. beamer depends
on pgf an xcolor. I thought it is convinient to add dependencies to 
packages beside that collections depend on collections.
I'm aware that there was never a complete dependency tracking planed.
