cutealien 439667b369 Speed up stl format loading, especially with text format.
Loading whole file now in memory (unless it's already a memory file).
And avoiding lots of memory allocations otherwise by buffering token string in class object.
Was a bit unusable before for large files (several minute loading times now down to a second)-
