ENH: Added SceneViews and Segment plugins to subject hierarchy

SceneViews is a role plugin for scene view nodes. Provides an icon and allows restoring scene views (request of Sonia)
Segment is a function plugin that adds a context sub-menu ("Segment this using...") to volumes. There is only one action under the sub-menu so far that takes the user to the Editor module, sets the volume as master and creates a labelmap as merge volume.

COMP: Add support for building on windows using Qt 4.8.6 and OpenSSL 1.0.1h

For more details see inlined comment. Also copied below for convenience:

8<----8<----8<----8<----8<----8<----8<----8<----8<----
# Starting with Qt 4.8.6, we compiled [1] OpenSSL binaries specifically for each
# version of Microsoft Visual Studio. To understand the motivation, read below.
#
# As explained in [2][3], if a library meets these two conditions:
#   (a) exposes a pure C interface
#   (b) is linked against static version of the CRT
# the version of the compiler and runtime used to build the library
# shouldn't matter.
#
# That said, since OpenSSL is built as a shared library using the '/MD' [4]
# flag, it is not possible to use the same library with different runtime
# libraries.
#
# We found out that '/MD' was used by inspecting the the file 'ms/ntdll.mak'
# generated atfer configuring OpenSSL.
#
# If you find mistake in this explanation, do not hesitate to submit a patch
# to fix this text. Thanks.
