* Make Ctrl+Enter (quick submit) work for issue comment and wiki editor
* Remove the required `SubmitReviewForm.Type`, empty type (triggered by quick submit) means "comment"
* Merge duplicate code
Since we are using EasyMDE now, we do not need to keep the SimpleMDE code anymore.
This PR removes all legacy SimpleMDE code, and makes some related changes:
* `createCommentEasyMDE` can accept native DOM element, and it doesn't need `jQuery.data` to store EasyMDE editor object (as discussed about the frontend guideline).
* introduce `getAttachedEasyMDE` to get the attached EasyMDE editor object, it's easier to find all the usage of EasyMDE.
* rename variable names from `$simplemde` to `easyMDE`, the `$` was incorrect because it is a EasyMDE editor, not a jQuery object.
With this PR, it will be easier to do more refactoring or replacing EasyMDE with other editors.
* fix: show client-side error if wiki page is empty
Implement a JS, client-side validation workaround for a bug in the upstream
editor library SimpleMDE which breaks HTML5 client-side validation when
a wiki page is submitted.
This allows native, client-side errors to appear if
the text editor contents are empty.
