Finds the name of a NewGRF in the list of names for unknown GRFs.
An unknown GRF is a GRF where the .grf is not found during scanning.
The names are resolved via UDP calls to servers that should know the name, though the replies may not come. This leaves "<Unknown>" as name, though that shouldn't matter very much as they need GRF crawler or so to look up the GRF anyway and that works better with the GRF ID.

Removes duplicates from lists of GRFConfigs.
These duplicates are introduced when the _grfconfig_static GRFs are appended to the _grfconfig on a newgame or savegame. As the parameters of the static GRFs could be different that the parameters of the ones used non-statically. This can result in desyncs in multiplayers, so the duplicate static GRFs have to be removed.
This function assumes that all static GRFs are placed after the non-static GRFs.
