Threaded comments – weekly update

This week I wrote inline comments for the code, and started writing some more robust documentation for some parts of it. Wrote on-screen help for users, and internationalized the plugin. Added security checks using nonces, and played with whitespaces and style. Also, as usually, fixed a couple of glitches, and performed some more checks and tests. Next week is about finishing documentation, fixing remaining glitches, and testing, testing, testing.
