Replace the term 'Basic' in Package Titles

It was decided that the term 'Basic' is new and
has no established meaning in the software community.

So, Replacing the term 'Basic' with 'Common'. To disambiguate
multiple instances of 'Common', we use an already existing term
'Primitive' and we also append the Platform to which the package targets.
