export more plugin headers

[Taras Glek <tglek at mozilla dot com>]

Hi,
This patch exports enough headers such that my plugin can compile 
without using the build directory. The hard part was figuring out how to 
export C++ headers.

Joseph, thanks explaining how to add a new target to language makefiles.
