build: Fix missing definition of uint64_t

On gcc 4.8.2 (fedora 20) without c++11 enabled the definition of
uint64_t is missing.  Switch to the pcl typdef for boost::uint64.
Add CMake option to enable/disable short file names in Doxygen

Commit 3f363a enabled short file name generation in Doxygen to address
filesystem limitations that arose while packaging PCL. However, for the
purposes of online documentation, short names are not acceptable as they
change with every build. This makes referring to function/class
documentation impossible.

This pull request adds a CMake option `DOXYGEN_USE_SHORT_NAMES` which
affects the corresponding Doxygen option. By default it is set to `OFF`,
i.e. generated file names will be long and descriptive, just like this
used to be prior to the aforementioned commit.

Fix build issues for Visual Studio 2008
build: Fix issue with windows library suffixes

Currently when using PCLConfig.cmake the libraries are searched with a
suffix of either _debug or _release.  When building with either
RelWithDebInfo or MinSizeRel these are not preoprly setup in the
CMakeLists.txt

As result when building with RelWithDebInfo you get libraries named
pcl_io.dll

but the PCLConfig.cmake looks for pcl_io_release.dll

This patch adds the release suffix to both RelWithDebInfo and
MinSizeRel to solve the problem.

provide stdint.h

PCLVisualizer: save and restore camera information

Press ctrl + s to save camera parameters and ctrl + r to restore the
saved camera parameters.

If a camera file is specified with "-cam" option or pcd file(s) is(are)
available in the command line, the camera parameters will be written to
the corresponding file and can be restored later from that file.
In this case, PCLVisualizer will restore camera parameters automatically
from the corresponding file when the pragram restarts with the same
command line input.
Replace gtest with sytem version

- Add new FindGtest.cmake to find installed versions.
- Add libgtest-dev for Travis
Added an additional vector<short> which keeps track of mappings from
centroid clusters to VFH signatures -- which occurs when axes can't be
disambiguated.

Also, ensured that the width and height are set properly on output when compute,
computeFeature, and computeRFAndShapeDistribution are called.
