Subject: Add long./lat./zoom URI parameters to simple UI

Instead of reading the longitude, latitude and zoom options from the
user / server configuration, one could use the new longitude=,
latitude= and zoom= URI parameters, in order to define the launch map
view. This is especially useful, in case you would like to embed
multiple maps with different views into e.g. another website.
