Another update for the build system

- .gitignore
src/unistd.h is not on src directory anymore (windows version is on winbuild directory)

- doxywizard.pro.in
consistency 0bj -> ../../objects

- Doxygen.sln
build doxygen 64 bit debug too

- Doxygen.vcproj
Config was missing (cannot be automatic due to the fact that there are 2 rules in 1 file), see also Doxywizard.vcproj

- Doxywizard.vcproj
consistency in respect to directories
$(QTDIR)/mkspecs/msvc2005 -> $(QTDIR)/mkspecs/msvc2008
settings part was present for x64 but not for Win32 (x64 not necessary for doxywizard)
Config_dw was missing (cannot be automatic due to the fact that there are 2 rules in 1 file), see also Doxygen.vcproj

- Version.rules
version.py does not need any arguments

- doxyindexer.vcproj
consistency in respect to directories

- doxysearch.vcproj
