split instruction into software installation and import

Basically leaves the part that needs to be done by the automatic
vagrant script in the bash script and moves the remaining part
into an OS-independent md file.

Also fixes some of the instructions for CentOS. Now almost runs
through (some minor issue with permission remains).

-# There are lots of configuration settings you can tweak. Have a look

-# If you plan to import a large dataset (e.g. Europe, North America, planet),
-# you should also enable flatnode storage of node locations. With this
-# setting enabled, node coordinates are stored in a simple file instead
-# of the database. This will save you import time and disk storage.
-# Add to your settings/local.php:
-#
-#     @define('CONST_Osm2pgsql_Flatnode_File', '/path/to/flatnode.file');

-# Downloading additional data
-# ---------------------------
-#
-# The following data is optional but download is strongly recommended:
-#
-#     sudo -u $USERNAME wget -O data/wikipedia_article.sql.bin http://www.nominatim.org/data/wikipedia_article.sql.bin
-#     sudo -u $USERNAME wget -O data/wikipedia_redirect.sql.bin http://www.nominatim.org/data/wikipedia_redirect.sql.bin
-#     sudo -u $USERNAME wget -O data/gb_postcode_data.sql.gz http://www.nominatim.org/data/gb_postcode_data.sql.gz
-#
-#
-# Initial Import of the Data
-# --------------------------
-#
-# **Attention:** first try the import with a small excerpt, for example from Geofabrik.
-#
-# Download the data to import and load the data with the following command:
-#
-#     ./utils/setup.php --osm-file <your data file> --all [--osm2pgsql-cache 28000] 2>&1 | tee setup.log
-#
-# The --osm2pgsql-cache parameter is optional but strongly recommended for
-# planet imports. It sets the node cache size for the osm2pgsql import part
-# (see -C parameter in osm2pgsql help). 28GB are recommended for a full planet
-# imports, for excerpts you can use less.
-# Adapt to your available RAM to avoid swapping.
-#
-# The import will take as little as an hour for a small country extract
-# and as much as 10 days for a full-scale planet import on less powerful
-# hardware.
-#
-#
-# Loading Additional Datasets
-# ---------------------------
-#
-# The following commands will create additional entries for countries and POI searches:
-#
-#     ./utils/specialphrases.php --countries > data/specialphrases_countries.sql
-#     psql -d nominatim -f data/specialphrases_countries.sql
-#     ./utils/specialphrases.php --wiki-import > data/specialphrases.sql
-#     psql -d nominatim -f data/specialphrases.sql
