In some cases, a POST might be sent to the server and there be no draft. In
such a case, neither the draft nor the body of the page can be inspected for
images. Even worse, in some cases the previous images might be unlinked from
the article without being relinked. Therefore, the images will no longer be
linked to the page and will likely be purged from the system.

Also add a drop-down list of common links include ticket links and login
pages for both agents and end users.

Names parsed from incoming emails are stored in the database as is. This
pull request addresses potential XSS vulnerability due to improper display
of unsanitized names. Going forward names will be scrubbed on create.

pjax:complete is only called after an AJAX page load. If a user navigates
forward or backward and the page loads from local cache, then pjax:complete
is not fired. pjax:end, however, is always fired.

Add original and last message quotes to canned responses

Otherwise, no column will be added to the %ticket__cdata table and the
ticket queue pages will be crashed (empty).

The default mode going forward will be to insert when Rich Text support is
enabled and append otherwise. To clear the draft the user can simply click
reset or delete draft icon on the bar.

Enable delete draft option on reply & internal note boxes for consistency.

If the advanced search dialog is up, avoid refreshing the page

htmLawed stripped/discarded <div> tags nested inside inline tags such as
<a>. The previous replacement engine would replace <img> tags with <div>
tags and would cause the HTML to be corrupted by htmLawed.

This patch uses <span> tags which have CSS rules to be displayed as
inline-blocks. This should stay truer to the normal sizing and placement of
the original <img> tag.

And use admin-defined site logo
