Add ability for user to edit own post

[C-Lodder]

• [x] - Add edit button next to delete button
• [x] - Initialize Ajax request on click
• [x] - Check timestamp in database and compare with current one
• [x] - Get shout data from the database and append to the form fields
• [x] - Change submit button text to "Update"
• [x] - Update the shout
• [x] - Add button to cancel the edit
• [x] - Make a parameter
• [x] - Use Language strings
• [x] - Revert back to "submit" button after update
• [x] - Add support for "enter to submit"
• [x] - Styling

  Bugs:

• The data attribute shout-id is updating in the HTML but it's not retrieving the new value when editing a different post after the first was edit. It's as if the events are not delegated when they actually are

You really do need a time limit on this. People shouldn't be able to edit their mosts more than 5-10 seconds after making them in a shoutbox

That's the plan
