#38: now remembers last visited directory

[ojob]

This works by file selection using the GUI, or by file addition with a
drag&drop operation.

These I201 / I202 errors are really annoying, particularly when last commit for Photocollage v1.4.4 raised no complaints, and when I made no change to these lines. RRh.

I've tested it and it works good!

However I would prefer last_visited_dir and folder to default to None, and not calling Gtk.FileChooserDialog.set_current_folder() when we don't know what dir to show (i.e. on first use). This way, "recent files" would be shown instead, which is pretty handy. What do you think?

About commits: please don't use GitHub-specific things in commit titles (like issues numbers or usernames), it's hard to understand when reading emails, in git log or when rebasing. Also this project uses Linux commit messages style for consistency and readability: this would give something like "gtkgui: Remember last visited directory" (feel free to read the commit log for examples!)

The following would be more Pythonic and more readable, what do you think?

    def __init__(self, folder='.', **kw):
        super(PreviewFileChooserDialog, self).__init__(**kw)

        self.set_current_folder(folder)

Comments appreciated and agreed! I made the changes. (Well, almost all: may I avoid rebase-ing the commits to update the wordings?)

I also added the persistance of output folder selection.
