static |
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.
