remove yandex mml dependency

[nvkelso]

These two layers depend on the Yandex table:

poi-station-labels < necessary
osm-place-points < depreciated

This is likely because the copy of OSM on server 1 is older than on server 2.

Changing these reference to

<!ENTITY project_host "localhost">
<!ENTITY project_port "5432">
<!ENTITY project_name "yandex">
<!ENTITY project_user "yandex">
<!ENTITY project_pass "">

To be osm_host, etc will likely resolve itself on server 2.
