Details:

Hello!  I'm attaching a patch to log the collection-status command in a
machine-readable format.

In the course of doing this, I changed a few things about log.py:

1) I added a flag to force logging of a particular message, regardless of
what the verbosity level is.  This is useful for when the user ran 'duplicity
collection-status' and we *know* we want to print it.

2) I set level names for all the verbosity levels.  The problem was 'how
would a consumer know how to process a level 8 message?'.  Up to now,
duplicity just didn't spit them out.  So I changed it so that several levels
together have the same keyword.  For example, level 5 is INFO.  All levels
above it (up to DEBUG) are also now INFO.  This way, all messages get properly
output to the log.

3) I made a minor modification in how the MachineFormatter formats the text
so that only the user-text-hint part gets prefixed with ". ".


The format I chose for the actual logging of collection-status is similar to
the overall logging format.  Here's a sample output:

INFO 3 
backend LocalBackend
archive-dir None
chain-no-sig 0
 full 2008-12-13T10:41:26-05:00 1

You can see the user-text is still there in case a wrapper wants to print
that.  But above it, you have several lines with sub-keywords and an indented
list of sets.

It's a bit made-up, but it seemed a reasonable extension.
