Mapsforge render themes

Hi,

first of all, thanks for supporting the mapsforge .map-files.

At the moment, the rendering rules are hardcoded in mapsforge. However, there's a render theme mechanism in development which makes it possible to define custom render rules in xml-files and changing the render theme using the api.

I don't know if you are aware of this. It would be great if Oruxmaps wil support these render themes once the development of the render-mechanism has finished.

To be more specific:
The function for setting a theme is "setRenderTheme(String renderThemePath)" in MapView.java of mapsforge.
So it seems that OruxMaps would have to offer a FilePicker or similar for chosing a Theme-File and then passing the path of this Theme-File to this function.
