KML download should not be limited

[mnalis]

the web display of course must be limited as it is currently to 100 pictures (as web2.0 browser loading thousands of thumbnails on each move/zoom would be very painful), but downloading KML for external program parsing/usage should not be (or at least the limit should be two orders of magnitude higher).

I think there still needs to be limits but there needs to be the option of requesting the next page of results too.
