#1 Move inode access time to imap

[Jason J. Herne]

Move access time from Inode to imap. This sounds
crazy, but it means that an inodedoesnt have to be
re-writen every timne its been read.

Imagine searching your whole FS for a file containing
the word "elephant". EVERY INODE will have to be
re-written to the end of the log!! THIS IS BAD!!!

This idea came from John Ousterhout himself ;)
