Changeset 6896 in josm for trunk/src/org/openstreetmap/josm/gui/mappaint/StyleSource.java

Message:

mapcss: add support for @media expressions
includes part of the style sheet under certain condition
e.g. min josm version.

There is a major limitation: the intire file is still parsed.
So if new syntax is introduced, it will still generate
a parsing error for old josm version even if the new code
is wrapped in an @media section.
