Fix shadowed variable 'facets'
Fix gitignore for sln/vcproj

 - The DevStudio/msvc build does not work for shared libraries (dll)
 - Fixed QhullFacet::PrintRidges to check hasNextRidge3d()
 - Cleaned up Qt project files
 - Fixed Makefile for shared libraries
 - Moved libqhull to libqhullstatic, as done in CMakeLists
 - Made libqhull a shared library
 - Restored /INCREMENTAL:NO since CONFIG -= incremental did not work
 - Added 'facets' argument to user_eg3.cpp

 -   Use shadow build directory instead of tmp (QtCreator's default)
 -   Moved targets to bin and lib
 -   Build static libraries for ease of distribution
 -   Remove VPATH
 -   Remove gcc options from DevStudio builds
 -   Remove QhullError.cpp and QhullEvent.cpp (empty files)
 -   Do not remove app_bundle from CONFIG
 -   Make -fno-strict-aliasing conditional on gcc version
 -   Added src/qhull-app-cpp.pri and src/qhull-app-c.pri for common settings
 -   libqhull.pro: Comment out -Wno-sign-conversion
 -   gcc warnings need fixing.  Does not build with gcc 4.4 and warn_on
 -   Moved projects/debian to src/debian.  Needs reorganizing

Code changes
 - Renamed RoadError::defined() to RoadError::isDefined()
 - Renamed RoadEvent::defined() to RoadEvent::isDefined()
 - Use fabs() instead of abs() to avoid accidental conversions to int
 - qconvex.c,etc.: Define prototype for _isatty
 - Rename parameters to avoid overriding other methods
 - qt-qhull.cpp: Move QHULL_USES_QT before the includes
 - qhulltest.cpp: Add closing prompt.

Need to update .pro and build files.

Create libqhullp.a with qh_QHpointer=1 for qhullcpp.dll, etc.
  gcc has halved the cost of qh_QHpointer by using more space
Add <time.h> to user.h for CLOCKS_PER_SEC
Move ostream<<QhullFacetList from inline to compiled.
  It tripped a double define error like the other classes.
Remove ptr_intT from qh_matchvertices.  Not needed.
Fix name of qh_QHpointer

Moved qtpro/ and vcproj/ into project/
Updated documentation for 2010.1
Add reviewed results of q_test and qhulltest
Fixed an error message

Added project files for qhull programs
Changed qh_gethash to return an int
Changed qh_addhash to take an int

Organized src/Changes.txt
Updated copyright dates
Fixed warnings from Kent William
Reviewing FIXUP
Add qhull-all.pro to build projects in order
Passed 127 tests.
