GenericProject: Support forwarding flags to clang code model

...in order to specify e.g. the language version to use.

Create the additional files project.cxxflags and project.cflags. These
are expected to contain command line flags for the clang code model on
one single line.

For example, "-std=c++11" can be provided to set the language version
for parsing.
