Adding -e to rtmpdump.
So instead of:
rtmpdump -r <url> -o <file>
we will have
rtmpdump -e -r <url> -o <file>
If <file> doesn't exist, it will be created. So the -e switch doesn't
change anything.
If <file> alredy exists, then rtmpdump will try to complete a previous
download.
That way, if videoob download <id> fails, running the command again
will complete the download without starting again from scratch.
There is now a "latest" collection (or "latest_nsfw").
The feature didn't look much used, since it didn't work on many
backends.
Using collections will make it easy to support other things
like most viewed, featured, etc.
As a bonus, I added tests for every backend with the feature.
* Remove callbacks in Collection object
Make Collection a "dumb" object (and also a base object,
though it isn't very useful for now)
* Rename Path to WorkingPath, because it is more about managing state
than being a single path.
* Rewrite almost all WorkingPath, because the code was overly
complicated for no reason (I tried some special cases and it turned
out that fromstring didn't handle them, and that the
quote-escape-unquote was just unecessary). I also rewrote it to be
more pythonic (no more lambdas and maps) and added tests.
* Require the full split path when creating a Collection. Because, come to
think of it, an object needs an unique identifier; in the case of
Collections, it is the full path, not only its last part.
I might even replace the id by the full split path in the future.
* There is now only one way to get items of a Collection: calling
iter_resources().
* Rewrite flatten_resources to iter_resources_flat(), which just calls
iter_resources() recursively.
* Rewrite the collection part of the canalplus module. There is no more
callback or a page calling the browser to check another page!
The logic is only in iter_resources().
The resulting code is not very pretty, but it should get better.
As a bonus, avoid to reload the main XML file when we already have it
open.
* change_path() now expects a split path and not a string.
* up/home special cases for "cd" are handled in the same place, and
store the previous place properly (but are not yet exploitable by
an user command).
This is a big commit but it would be hard to split it in *working*
commits.
If you read this entire commit message, I will buy you a beer.

Use stderr and return codes >0 when it makes sense.
Loose return code conventions:
* 1 for generic errors
* 2 for user input errors
* 3 for remote errors (not found, etc.)
* 4 for not implemented
