Documentation: Added some crossreferences for *.secure().
Added nano-second resolution file-timestamp support to stat
Add locking support to FUSE.

Also implement the nano-second version of utime.

They were never exactly part of any standard.

The rest of the documentation is now extracted as well.

filesystem isn't used.
More static.
Decomplex the lookup function a bit.
More documentation for Image.XCF and Image.PSD.
