change rendering style of "non connected nodes"
|Reported by:||anonymous||Owned by:||framm|
because not every user understands that nodes have to be connected in order to do routing on the map i suggest a changed rendering style when they are.
nodes that only form a line stay red
nodes with three edges turn yellow and increase in size
nodes with four edges turn green and increase in size even more
and so on
this would lead to a quick validation without any need for plugins
