Should help the human beings using uReadIt to write with markdown

Hi,

Comment and text post submitted on reddit are markdown formated. User should be able to have like on reddit.com, at least a help format remminder.

For example, on the text input in a comment/text post page, a help button should be visible to display common markdow reddit usage.

I did a pro mockup on the attachement file below :
 * On the left side: reddit
 * On the right side target uReadIt
 * Carefull, missing a close button for the help page/popup in the mockup
 * An enhancement of this could be to add a toolbar with some basic B, I, U, list, code, quote, full-line, buttons (see http://www.reddit.com/wiki/commenting )
