To Do list: add & remove

[chaw-bot]

This pull request adds the following changes to the repository.

• Remove all hardcoded items from the tasks array.
• Create a new JavaScript file for the add/remove functionality.
• Implement a function for adding a new task (add a new element to the array).
• Implement a function for editing task descriptions.
• Implement a function for deleting a task (remove an element from the array).
• Implement a function for the "Clear all completed" button (use filter() method).
• By default new tasks should have the property completed set to false and the property index set to the value of the new array length.
• Deleting a task should update all remaining items' indexes, so they represent the current list order and are unique.
• All changes to the To Do List should be saved in local storage.
