Allow recipes to be created non-interactively

[blee]

It would be nice if recipes could be created non-interactively.

I think we should support a "-F" flag with the same semantics as
svn. Or maybe we should use that for logs and support "-R" to
specify the recipe in a file?

[ccowart]

In [462] Reworked the way in which confman handles opening an EDITOR for
recipe editing and log message capturing.

This implements a reasonable template for recipe files providing better
context clues to the user. See #83.

This also allows recipes to be created non-interactively. After adding
the -R flag to confman recipe create, it became obvious that unless
the svn logs could also be captured with something like -m or -F
(similar to actual svn client behavior), that things wouldn't be totally
non-interactive. A lot of rewriting of log handling has happened, touching
both the install and commit functions in addition to the recipe editor.
See #84.

Due to the large extent of these changes, let's make sure it gets a good
round of testing in several environments before we clear it to be merged
into the 1.9 branch.

The referenced tickets will remain open until the merge has happened.

(In [464]) I've significantly improved the new log message handling features.

The -m/-F now are expected in the more intuitive placement of after the
command they modify (just like svn).

They were also adopted to the recipe create, edit, and remove commands with
their new placement.
