Some conversions:

1) Converted some parts of the functions in the util namespace to the new file handling

Note:

1) The ONAM functions are still not much more than a description of the ideas that ran through my head at the time and still don't work and still need to be fully rewritten for the new handling. They also probably will need to update the file size sections.
2) The create master and reversal functions should now work as advertised. However, each one assumes that the file's status is opposite of that of what the functions do. That is, createMast assumes the file is not a master and revCreateMast assumes it is a master with the flag set in the file. If this is not so, then the functions do the opposite: a master is no longer a master based on the flag with the createMast function and the same is true for revCreateMast with a non-master. The isMaster function of the espm namespace can help with this.
