copy method for reader plugins (called when SCIP copies plugins)

static SCIP_DECL_READERREAD ( readerReadSol  )
static

problem reading method of reader

In order to determine the type of the file, we have to open it. Thus, it has to be opened twice. This might be removed, but is likely to not hurt the performance too much.
