This is the next stage of recipe reorganization, in this stage
many recipes where moved to a new meta-demoapps layer since this
is more appropriate for demo usage then the core. Additional some
recipes were moved to meta-extras to indicate they may be depercated
at a future time.
A number of recipes were modified since dependencies need to be
corrected.
