Fix invalid Atom feeds when using emoji, horizontal rules, or images
This is a fix for issues #880, #723, #1113.
Markdown must be rendered to XHTML, not HTML, when generating summary content for Atom feeds. Otherwise, content-less tags like *img* and *hr* are not terminated and make the Atom XML invalid. Such tags are generated when issue descriptions, merge request descriptions, comments, or commit messages use emoji, horizontal rules, or images.
To pass this option through from the relevant Haml templates to the proper place in the `gfm()` method, a new method `gfm_with_options()` is introduced. It reuses the options dictionary passed to `markdown()` and interprets options `xhtml` and `parse_tasks` from it (the latter was a convenient replacement for `gfm_with_tasks()`). `xhtml` is already interpreted by Redcarpet::Render::HTML, but that alone was not sufficient, because the post-processing in `gfm()` would convert its XHTML tags back to HTML.
I found no way of passing additional optional options to the existing `gfm()` method without requiring updates to existing callers and without getting in the way of the existing optional arguments, but maybe someone who knows more about Ruby than I can think of one.
Thorough review appreciated since this is the first time I have used Ruby.

Fixes issues #880, #723, #1113: Markdown must be rendered to XHTML, not HTML, when generating summary content for Atom feeds.

Make the Markdown parser recognize "[x]" or "[ ]" at the beginning of a
list item and turn it into a checkbox input. Users who can modify the
issue or MR can toggle the checkboxes directly or edit the Markdown to
manage the tasks. Task status is also displayed in the MR and issue
lists.
Jira issues numbering format are like: "PROJECT-1234".
Changed the regular expression to support Jira issues linking, in addition to the normal #123.
Added Jira Issue tracker configuration example
