* info: Can now display info about a given uuid.
* Added to remote/uuid info: Count of the number of keys present
on the remote, and their size. This is rather expensive to calculate,
so comes last and --fast will disable it.
* Git remote info now includes the date of the last sync with the remote.

Unfortunately, this caused breakage on Windows, and possibly elsewhere,
because parentDir and takeDirectory do not behave the same when there is a
trailing directory separator.
I think this is the last problimatic setCurrentDirectory. I also audited
for extrnal commands that git-annex might run with cwd = foo, and did not
find any that were passed any FilePath that might be absolute.
parentDir is less safe than takeDirectory, especially when working
with relative FilePaths. It's really only useful in loops that
want to terminate at /

This allows the git repository to be moved while git-annex is running in
it, with fewer problems.
On Windows, this avoids some of the problems with the absurdly small
MAX_PATH of 260 bytes. In particular, git-annex repositories should
work in deeper/longer directory structures than before. See
http://git-annex.branchable.com/bugs/__34__git-annex:_direct:_1_failed__34___on_Windows/
There are several possible ways this change could break git-annex:
1. If it changes its working directory while it's running, that would
be Bad News. Good news everyone! git-annex never does so. It would also
break thread safety, so all such things were stomped out long ago.
2. parentDir "." -> "" which is not a valid path. I had to fix one
instace of this, and I should probably wipe all calls to parentDir out
of the git-annex code base; it was never a good idea.
3. Things like relPathDirToFile require absolute input paths,
and code assumes that the git repo path is absolute and passes it to it
as-is. In the case of relPathDirToFile, I converted it to not make
this assumption.
Currently, the test suite has 16 failures.
In the case where a remote of the bare repo has a fetch = configuration,
refs/remotes/origin/master will exist, and so the merge code path tried to
run in the bare repo.
The url log could have an url for a key, while the location log thinks it's
not present in the web. In this case, addurl --file url would not do
anything. Fixed it to re-add the web as a location.
I don't know how this situation could arise, but I saw it in the wild in
the conference_proceedings repo, affecting key
URL-s17806003--http://mirror.linux.org.au/pub/linux.conf.au/2014/Wednesday/53-Building_Effective_Alliances_around_the_Trans-Pacific_Partnershi-c0505b631127ccc67e38e637344d988e
Investigating the presence log, it looked like that key
was originally listed as present in the web, then in commit
56abf9e9f3e691ed9d83513037d4019313321ca3 someone else's git-annex
set it and some other things to not present in the web. It would be
interesting to know what that user did, but I doubt I'll be able to find
out. All I can tell from this investigation is that the inconsistency was
not introduced when originally addurl-ing the url.
This allows bypassing the direct mode guard in a safe way to do all sorts
of things including git revert, git mv, git checkout ...

I had hoped that the git devs could change git's handling of partial
commits to not use a false index file, but seems not.
So, this relies on some git internals to detect that case. The test suite
has a test case added to catch it if changes to git break it.

Now `git annex info $remote` shows info specific to the type of the remote,
for example, it shows the rsync url.
Remote types that support encryption or chunking also include that in their
info.

This avoids making the parameters column quite wide, which caused
descriptions of other commands to not fit in 80 cols in the usage display.
FIELD=VALUE is a simplification, but so was the old display. The man page
gives more detail.
This is not a complete fix. For one, git remote will happily go add a
remote that has the same name as an existing special remote. For another,
enableremote will enable a special remote over top of an existing git
remote. And, also, the webapp might.
