Prevent html injection

Commits page renders commit description with single_format method which allows html tags. So commit message with html tags brokers Commits page. See screenshot

Get Reply button as clicked target in notes.js.coffee

See issue #401

This is a small fix to properly find the reply button as the click target when an element inside the button is clicked (e.g. in this case, the ``<i class="icon-comment">`` element in the button, using the jQuery ``.closest(...)`` function.

Previously, the clicked element was assumed to be the button itself, which caused the comment form to spawn within the button when it was clicked (see the issue for screenshots & other details).
