WebDAV needs this to clean up empty collections. Also, example.sh turned
out to not be cleaning up directories when removing content
from them, so it made sense for it to use this.
Remote.Directory did not need it, and since its cleanup method for empty
directories is more efficient than what Command.Export will need to do
to find empty directories, it uses Nothing so that extra work can be
avoided.

Apparently box.com renaming is just buggy. I tried a couple of fixes:
* In case the http Manager was opening multiple connections and reaching
different backend servers, I tried limiting the number of connections
to 1. Didn't help.
* To make sure it was not a http connection reuse problem, I tried
rewriting how exportAction works, so that the same http connection
is clearly open. Didn't help.
So, disable renaming of exports for box.com. It would be good to test it
with some other webdav server.

It was not getting old lines removed, because the tree graft confused
the updater, so it union merged from the previous git-annex branch,
which still contained the old lines. Fixed by carefully using setIndexSha.

This breaks backwards compatibility, but only with unreleased versions of
git-annex, which I think is acceptable.

This basically works, but there's a bug when renaming a file that leaves
a .git-annex-temp-content-key file in the webdav store, that never gets
cleaned up.
Also, exporting files with spaces to box.com seems to fail; perhaps it
does not support it?

In a test, I uploaded a pdf, and several files were derived from it.
After removing the pdf, the derived files went away after approximatly
half an hour. This window does not seem worth warning about every time.
Documented it in the tip.
Removal works, only derives are a potential issue, so allow removing
with a warning. This way, unexporting a file works, and behavior is
consistent with IA remotes whether or not exporttree=yes.
Also tested exporting filenames containing unicode, spaces, underscores.
All worked, despite the IA's faq saying it doesn't.

It opens a http connection per file exported, but then so does git
annex copy --to s3.
Decided not to munge exported filenames for IA. Too large a chance of
the munging having confusing results. Instead, export of files not
supported by IA, eg with spaces in their name, will fail.

Only rename when actually ncessary.
The diff gets buffered in memory. Probably git has to buffer a diff in
memory when generating it as well, so this memory usage should not be a
problem, even when the diff is very large. I hope.

Don't allow "exporttree=yes" to be set when the special remote
does not support exports. That would be confusing since the user would
set up a special remote for exports, but `git annex export` to it would
later fail.
