Add My Tasks view & dashboard widget

[nicolachr]

Summary

Currently, when methodology cards are assigned to users, the assigned users do not have a way to see which cards are assigned to them unless they manually go through each card. This is tedious and prone to letting cards fall through the cracks.

The proposed solution, allows the users to:

1. Use the dashboard widget to see the five tasks with the highest priority that are assigned to them. Highest priority is given to tasks that are overdue, and lowest priority to tasks that don't have a due date.
2. Access a dedicated "My Tasks" view that displays all the tasks that are assigned to them in the form of a table.

This will allow users to have better command of their tasks, make the process of finding a task easier, and will help the users stay on top of things.

Check List

• Added a CHANGELOG entry

The idea is to extend this to include other assignable record types in the future correct?

In order to leave this open for extension as easily as possible, we should check for record type before rendering the link_to and the <li> content since it will vary between record types

[MattBudz]

We can add a switch statement or a new helper method for this once we introduce another record type as a task

[caitmich]

If we're passing project_id we should use it here otherwise it could have unexpected results

Suggested change

	cards.select { |card| card.project.id == current_project.id }
	cards.select { |card| card.project.id == project_id }
