List improvements

This release is all about enhancements and improvements to lists!

• You can now duplicate an entire list with a tap of a button!

• You can now mark all tasks within a list as done, or not done, with a tap of a button too!

Use these in combination to easily create lists with pre-populated tasks, handy for creating lists such as holiday packing lists where you'd usually have similar things to pack as your previous holiday's packing list.

Let us know how you're using these features!
