Title: FIX: off-by-one in the monument code that resulted in redundant roads

This is just the bugfix part of the pave-the-planet patch: we should build monuments if there is at least one road neighbouring the monument, but the code checked the monument's neighbours-but-one for roads instead of neighbours.

If Junna is right, this bug is probably present in Standard as well.
