[OSM-dev] central elemstyles/MapFeatures.xml

[80n]

An earlier version version of Osmarender did have a mechanism to allow an
external style sheet file to be referenced.  I think it caused problems with
some tools because I didn't implement it properly, so it got dropped.

It should be easy to re-introduce this.  The styles are separate from the
rules for this exact reason.
