ask before allowing to move node that is attached to ways fully hidden by filters

[mkoniecz]

Typical mistake made by experience mappers is moving nodes with enabled filters and failing to notice that filtered out objects are attached to this nodes.

I suggest to raise window "Are you sure that you want to move node with attached ways that are hidden by filters?" in cases like this.
