This gives us more flexibility: after all how often does one have
a WebDAV server handy (unless you're smart enough to use HelioHost
or some other awesome server)?
These options make Seance go through the motions of processing a
post without actually uploading images and/or pushing them to
Ghost. This makes it easier to test out stuff for new features
(or, more accurately, it reduces the need to clean up afterwards!)
Earlier, it used to print out the stuff to the screen, which you'd
then have to copy to a file manually - tedious!
By the way, the other fixes were typos and omissions while changing
Seance from a simple file to an object.
