creation time from potential file metadata.
camput: add the -exiftime option that allows
the use of the above for -filenodes and -vivify.

We might tweak the parameters yet, and I want to add a bunch more
tests, but this is a major relief for me. I've been reluctant to
put too much data into my personal Camlistore instance until I
figured out how I wanted the file chunks to split.
This also simplifies (deletes) a fair bit of code.

This change introduces 2 features, illustrated by those examples:
1) camput file -filenodes *.jpg
This was not previously possible because -filenodes option only worked
with directories.
2) camput file -filenodes -tag 'nice pics' /media/foo/DCIM/
This was not previously possible because the -tag option could only be
used with the -permanode option.

A planned permanode involves setting the contents of the permanode
(instead of a random string) as well as the OpenPGP signing time so
the resultant bytes of the blob (and thus its blobref) is deterministic.
This allows multiple independent devices (my laptops) to create the
same permanodes for the same files (photos backed up from my phone)
when offline (airplane) and then when they sync later, still only have
one permanode per unique file. This means that tagging and other
metadata applied to permanodes on one laptop merge cleanly with
metadata from the other.
