COMP: Explicitly link RemoteIO against OpenSSL

Given that since commit r22724  curl library is linked against OpenSSL
and that since commit r22732 it is statically built. This commit
explicitly link the shared library RemoteIO against OpenSSL
because the curl static library doesn't provide information how to
resolve the OpenSSL symbol.

COMP: External_curl - Build only http/https support to avoid link error

By default, curl will try to build all supported features. Since only
http/https protocol is needed, let's simply disable the other feature
to avoid extra dependency to library like "ldap", "idn" ...

See #1739

COMP: External_curl: Fix build issue + Build against patched 7.34.0 release

This commit install the project so that all needed headers are all
in the same folder.

It also change the version of curl to 7.34.0 with an additional patch
adding CURL_STATICLIB to curlbuild.h to fix build issue on windows
and unix system.

Finally, it reverts r22728 which was incorrectly addressing the build
error described in the corresponding commit message.

COMP: Optionally configure Slicer inner project with OpenSSL options.

ENH: Updating RSNA Quant tutorial for 2013

Rename to more generic test name so it's not tied to a year.
Use new data sets from Sonia
Add screen shot GUI elements and flags and method, capture screen shots at tutorial steps.
Tweaked all parts to match up to tutorial (first part was already tested
in the Vis tutorial, swapped it out for the Ruler)
Updated CMakeLists.txt so that this commit is independent of the Vis tutorial commit.

Issue #3507

COMP: Removed unused/unmaintained RemoteIO classes and FetchMI module logic

For future references, the corresponding code has been added to
the Slicer attic. See Slicer/Attic@53262c8

From discussion with Steve and Andras:

// --------------------
(1) Jc - Nov 26, 2013

I notice that the only reason we depend on curl is for existence
of RemoteIO library that has been "replaced" by SampleData
and DataStore.

I really like the concept of registering URI that could be
downloaded that is why we should keep the infrastructure in place.

That said, I was thinking to get remove the following classes:

vtkHIDHandler.h
vtkHIDTagTable.h
vtkSRBHandler.h
vtkXNATHandler.h
vtkXNDHandler.h
vtkXNDTagTable.h

Then, we could implement a Qt based  vtkHTTPHandler handler, that
way we could simply remove the curl dependency.

In the mean time, I would also remove the FetchMI logic which is
not maintained or used at that point.

Let me know what you think,

// --------------------
(2) Andras - Nov 26, 2013

It’s always a good idea to make the core smaller and simpler, so
I support the idea of getting rid of unused classes and unnecessary
dependencies.

We planned to use curl for uploading training results in a .zip
file to Moodle, but I guess we can add curl to our module then.

// --------------------
(3) Jc - Nov 26, 2013

Thanks for commenting.

If your module is a loadable or a scripted module, all "curl"
functionality can be provided by Qt. Would that work for you ?

// --------------------
(4) Andras - Nov 26, 2013

We would need quite complex curl functionalities for uploading data,
see the scripts below:

https://gist.github.com/Joshkunz/4516316

https://github.com/proyectoeduhub/moodle-cli/blob/master/moodle-file-upload-curl.sh

Would it be feasible to implement these?

// --------------------
(5) Jc - Nov 26, 2013

Good point. The plan would then be to:

  (1) remove dependency of Slicer core against curl

  (2) Only, build both the Curl library and the curl executable, keeping
 them in the package.

That way, it would provide great flexibility with minimum overhead.

// --------------------
(6) Steve - Nov 26, 2013

Sounds like an excellent plan.

Yes, I like the design of the remote IO support in MRML, but it's not
 being used and is great to simplify wherever possible.  FetchMI can
go away for now, with the hope that we'll reproduce and improve on
it in the future (someday).
