Fixed bug in arg parsing

Some of the dummy options were declared has having an input parameter.
This caused some of the Gaudi genreflex commands to fail because
some headers were not found, for example Python.h.
This was was due to the fact that that inclusion was considered as
the parameter of the dummy option.
For example:
genreflex /build/nightlies/test/Tue/GAUDI/GAUDI_no_reflex/src/GaudiPython/dict/kernel.h -o ../x86_64-slc6-gcc48-opt/dict/GaudiPython/kernel_dict.cpp    --no_templatetypedefs -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../../../experimental/Python/2.7.4/x86_64-slc6-gcc48-opt/include/python2.7" --gccxmlopt='--gccxml-compiler lcg-g++-4.8.1 ' -s=../dict/selection_kernel.xml  --gccxmlpath=/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../../../experimental/gccxml/0.9.0_20120309p2/x86_64-slc6-gcc48-opt/bin --rootmap=GaudiPythonDict.rootmap --rootmap-lib=libGaudiPythonDict  -D_GNU_SOURCE -DGAUDI_V20_COMPAT  -DBOOST_FILESYSTEM_VERSION=3  -I"/build/nightlies/test/Tue/GAUDI/GAUDI_no_reflex/src/GaudiPython"  -I"/build/nightlies/test/Tue/GAUDI/GAUDI_no_reflex/src/InstallArea/x86_64-slc6-gcc48-opt/include" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../ROOT/ROOT_today/x86_64-slc6-gcc48-opt/root/include" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../ROOT/ROOT_today/x86_64-slc6-gcc48-opt/root/include" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../../../experimental/Boost/1.50.0_python2.7/x86_64-slc6-gcc48-opt/include/boost-1_50" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../../../experimental/xrootd/3.2.7/x86_64-slc6-gcc48-opt/include" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Settings/../../../../../experimental/AIDA/3.2.1/share/src/cpp" -I"/build/nightlies/test/Tue/LCGCMT/LCGCMT_danilo/LCG_Platforms/src"
