Text Editing Patch

We have reenabled the ability to input text on notes, posts, and anywhere else Markdown is used. In the interest of getting this fix out as quickly as possible, Markdown previewing has temporarily been disabled.

The cause was an issue with our Markdown library and we are actively working on a more long-term solution that brings back full functionality. We appreciate all of the users who reported this through the Help widget and apologize for the interruption.
