cldoc treats .hpp files as main files

[simonask]

When cldoc generates documentation for header files with the .hpp ending, they are treated as if they were .c/.cpp/.cxx files.

This is a problem, because Clang generates a warning when it encounters a #pragma once directive in a main file, and due to issue #3, this causes cldoc to exit immediately.

Having fixed issue #3, I've started looking at this issue. Unfortunately, I don't really see any way for libclang to indicate it should parse something as a header. Even worse, you can't rely only on a files extension to indicate whether it's a header or not. The "best" solution to this problem is to have a dummy .cpp file which includes the corresponding header, but it goes against the idea of cldoc to require zero modifications to the original source.

So this still generates a warning, but will still generate the right thing. I'm closing this for now.
