[sword-devel] Efficiently extracting section + chapter headers

[Tobias Klein]

Thank you so much, Troy! I appreciate it!
I'll give this a try soon! This will then probably turn into a new API 
function of node-sword-interface.

I will also check once more regarding the CMake zlib issue on Windows. 
Before that is fixed I can't really integrate new SWORD trunk versions.
