ENH: Add VTK 6 support 1/2

1) Support vtk6 to build system.
http://www.vtk.org/Wiki/VTK/Build_System_Migration
Give users a build option between vtk5 and vtk6.
Solve vtk library python wrapping for VTK 6
Use system zlib (this is a hack)
Use system png (this is a hack)

2) Update dependency projects in superbuild including VTK, CTK, OpenIGTLinkIF, MultiVolumeExplorer.

3) Remove deprecated Macro.
The following two macros were deprecated in VTK 5.0 that were still supported, but have now been eliminated:
vtkTypeRevisionMacro has been replaced with vtkTypeMacro; vtkCxxRevisionMacro has been removed.
http://www.visitusers.org/index.php?title=VTK_6.0_Upgrade

The following two macros were deprecated in VTK 6.0 if VTK_LEGACY_REMOVE is on:
VTK_LARGE_INTEGER and VTK_LARGE_FLOAT
https://github.com/Kitware/VTK/blob/9a0fbb8da1a1701dc1b44c71467b969b3302efad/Common/Core/vtkType.h#L158-159

vtkFloatingPointType is replaced with double.

COMP: Add FindFontConfig.cmake

FindFontConfig.cmake is from VTK.

VTKv6 was not built with the module vtkRenderingFreeTypeFontConfig because
it could not find FontConfig. However, once VTK was downloaded and
configured. Any find_package(FontConfig) call (e.g. in CTK) would succeed
because FindFontConfig.cmake is now in the CMake search path.

BUG: Fix missing search icon on some platforms

Use the CTK built-in fallback icon for the clear button in case loading
of the themed icon fails. This avoids having an invisible active click
area.

ENH: Disable search on extension details page

Tweak handling of the extension search field to disable it when looking
at the detail page of an extension, as it makes no sense in this case.
Also disable it (for now) when managing installed extensions.

BUG: Don't rely on URL change to update search

Also set the current search text (used to avoid unnecessary updates)
when applying the search filter. This way, the test still works if we
never get the URL changed signal (which seems to happen on some machines
for reasons unknown). In theory, since the URL change is being triggered
by JavaScript and not waiting on a server response, it should happen
immediately anyway, possibly even synchronous in the call to
evaluateJavaScript().

This should fix inability to clear the search text on some machines
(because failure to update the last search text means we always think
we have no search, and therefore don't need to do anything to clear the
search text).

BUG: Fix crash when loading volume

Some compilers (e.g. i686-apple-darwin10-g++-4.2.1) fail when using RTTI
with vtkDataArrayTemplate.
VTKv6 offers the FastDownCast workaround by internally using static_cast.
