MapParameters for accessing specific features of custom QGeoMaps

This patch adds a new MapParameter object to give users access to
specific features of a custom QGeoMap otherwise not accessible through
the standard API.

A MapParameter is implemented by a QDeclarativeGeoMapParameter, which,
in turns, inherits from QGeoMapParameter in the location module.

In this way QGeoMap & subclasses won't depend on declarative, from
this side, still allowing a QMapWidget someday.

The implementation is based, on both sides, on the dynamic
properties of QObjects for defining the MapProperty data.
This allows high flexibility in defining various types of
MapParameters (essentially by duck typing them), and therefore
each plugin which makes use of them must document each of them.
