[PATCH] Add nodes on intersections action

[Upliner]

There was the Intersect_way plugin that allowed to add nodes on intersections of ways. Unfortunately, author haven't published the source code and the plugin became unmaintatined and unusable. Since then similar functionality was implemented in "Join areas" action. I propose to extract addIntersections function to new action and share it with "Join areas". It's better than copy-pasting this function to new plugin.

add to /trunk/images

Isn't it easier to double click on the intersection point? Maybe it's not so well known, but it places the node at the exact point of intersection (because of snap effect).

Oh, I didn't know about this feature.
However, when drawing a grid of streets, the new streets creates a lot of intersections with existing streets and with each other. It's harder to point at them all. If you don't want to integrate this function in the core can you at least make addIntersections method public and static? It can also be used in the validator plugin making able to automatically fix the "crossing ways" error.

see #5577 (patch by extropy) - Move some methods and make them public static

Sure, i'm not saying it is totally useless, the method I described is not really documented after all...

In case you add a plugin, please call it 'toolsplugin' or something like that, so we can add other more specialized tools and helpers.

Added it to the new UtilPlugin2. (In [o24236])
