zoom controls for the slippy map

[flaimo]

i don't know why nobody noticed that, but when calling the download dialog, the slippy map doesn't have any controls for zooming in and out the map. it seems the programmer assumed, that everyone has a scroll wheel on a mouse or knows the keyboard shortcuts for zooming (which i think, still don't work on a mac). from a usability point of view i consider this a major bug, since this is the point where new users might already surrender and go back to potlatch if they can't even zoom in and out to a specific location.

I also have a mouse without middle button and without wheel.
There is no comment in the source code why the zoom controls are disabled:

Added parameter slippy_map_chooser.zoomcontrols, see #6997

I have added aadvanced parameter to turn zoom controls on.

But final decision suitable for newcomers is still to be discussed. Default controls does not look well enough to turn them on by default...

There's a strange bug when using the slider: the "+" icon displayed on the right is also displayed above the slider:

Maybe that is the reason why it is turned off :) (it does not appear every time on every system) We need help of JMapView component developers...

Which is mainly "@team" for some time now :-)

In [4866/josm]:

Add numeric keypad +/- support to zoom in/out in Slippy Map (see #6997)

I got it every time on Windows, I'll try to debug it this week :)

At least I've added +/- keys in addition of previous (ctrl/alt)/(up/down) to zoom in/out.
