Space Index and Cleanup

Removed the double-hash strategy from spaceindex.  Now a space(blank) configuration
indexes a vector of vector of EBMSes.

Also did some clean up with files.  Remove all newlines to save a 20th of the space (for CP24).
Replaced fprintf with write-bytes which will not need to check on formatting.  Since fringe files
no longer have newlines, had to also change the position counting functionality.
