Do not transform stderr messages into message boxes

[GoogleCodeExporter]

I get a couple of "standard" warnings here on startup of pretty much any 
program. MoNavC creates a warning box for each of them, which is highly 
annoying. Moreover, I get a couple "Reading ras files from sequential devices 
not supported" message when panning the map in the client, each of them 
resulting in a warning to click away.

I will most likely add a checkbox "ignore this kind of warning in the future" 
to the message dialog as well as global option to turn off notifications for 
specific warning / error levels completely.

Concerning you error messages: Are you using the OSMRenderer plugin? It might 
be, that the cache / temporary file folder, which is queried from Qt, is not 
accessible. It is used by the OSM Renderer plugin to store its network cache of 
downloaded tiles.

Yes, I didn't build the mapnik plugin, thus using osmrenderer.

I noticed that some plugins have a QtGui dependency because they use error 
messages/info dialogs as well. Would be nice if the plugins would only have a 
QtCore dependency and error/info dialogs would only be created by the (a) GUI. 
Maybe you can change that if it's not too much work.

Makes sense to remove any kind of GUI dependency from any non-rendering 
plugins, I will most certainly do this.

About that very annoying error message, don't know why that comes, but was easy 
to fix by just changing "image.load( reply, 0 )" to "image.load( reply, "PNG" 
)" in osmrendererclient.cpp.

Strange, Qt should be able to figure this out on its own... but thanks, I will 
include this change. It has the drawback that one can only load images from PNG 
tile servers, though.

What error do you exactly get and how can one reproduce it?

I get exactly that same error message "Reading ras files from sequential 
devices not supported", as many times as tiles are downloaded from OSM. Cached 
tiles does not show error. Sorry, I don't know how you could reproduce this 
error. This has happened always and as long as I have used MoNav.
