[PATCH] change default projection to marcator

[smsm1]

The following patch changes the default to marcator, since that is what the vast majority of mappers require for getting buildings square and many mappers complain.

Also defaulting to using api.openstreetmap.org.

We cannot change the default to Mercator as long as the WMS plugin will silently download EPSG:4326 landsat imagery and simply scale it to fit the Mercator box. This is all a bit ugly and nobody really understands it but if you use Mercator and Landsat then the stuff you draw will be off by more than a negligible amount... that's why we want users to know what they are doing. Agreed that it is not nice.

I have created another ticket for the real issue, please apply this patch to make life easier for users, and then get the WMS plugin fixed (which I imagine, only advanced users will use anyway).

WMS used EPSG:4326 for Mercartor as no WMS server supports Mercator projection and the differences between these two aren't so big when small tiles are used (as WMS plugin downloads in small tiles).

If the distorion is to big for nothern areas, then maybe we can change WMS plugin to download smaller tiles in these areas.
