Only displays the todo body if the todo has a note.
This is to avoid redundant Issue or Merge Request titles
displayed both in the Todo title and body.

Currently, we label items to be done as "Todo." This is grammatically
incorrect and (therefore) confusing—especially to our Spanish-speaking
users for whom "todo" has a specific and unrelated meaning.

We should use "To Do" and always use it as singular (not "To Dos").

Improved todo message when an issue is assigned to yourself.
- The new message when an user assign to himself an issue or a mr is: "You
assigned issue xx to yourself"
- The new message when an user adds a todo to himself is: "You added a
todo for issue xx"
- The new message when and user mention himself is: "You mentioned
yourself on issue xx"
- The new message when an user directly address himself is: "You
directly addressed yourself on issue xx"
- The new message when an user mark himself as an approver is: "You set
yourself as an approver for merge request xx"

in the 'Todo' tab of the Todo dashboard.
The operation undos only the todo previously marked as done with the 'Mark al as done' button.

Added the ability to 'Undo' the todos marked complete in the 'Done' tab of the Todo dashboard.

When a build fails for a commit, create a todo for the author of the
merge request that commit is the HEAD of. If the commit isn't the HEAD
commit of any MR, don't do anything. If there already is a todo for that
user and MR, don't do anything.

Current limitations:
- This isn't configurable by project.
- The author of a merge request might not be the person who pushed the
  breaking commit.

* Introduce 2 color links: black and blue
* Use black color link for UI elements like lists
* Refactor lists to use .title nested under li
* Make all lists (events, todos, activity, projects etc) use style
* List colorschema is now 333 for links and 555 for text
