Update: quick reply and custom icons

[absolut]

Hi folks, two quick updates

* added ability to have quick reply for comments
* quick reply is disabled by default (To enable, set "Enable the quick reply form when replying to comments?" to "yes")
* added code for new custom security icon (thanks hsapiens)

Next I'm going to look into these two posts since I missed them when they were first posted.

Thank you so much for updating with the new custom security icon. I nearly had a panic attack when I saw all the locked icons had gone before I realised what had happened!

It's so good to know that you're still taking the time to update this layout too. It's the best one I've used and I've never taken it off since it was first available. Thank you!
