Description:
There are some last hard-coded references to Wikipedia in the system messages
names. Here I fix "nstab-wp" (which means "nstab-wikipedia") to "nstab-project",
and "wikipediapage" to "projectpage". Also, I fix a hard-coded reference to
"Wikipedia:Metadata", to "{{ns:project}}:Metadata".
