[Modules] Update "add item to module" UX design

[Ingridrnilsen]

Problem statement:

Add item to module isnt very intuitive for teachers. The fact that you have to chose what to upload is okay, but then have to press "New Assignment" in brackets in the exact same design as the other assignments under

Proposed solution:

button for add new item? with clear ux design pulling your eyes towards it. could barely spot it first time around previous can be in the box other items on the room can be in a little box still.

User role(s):

admin,instructor,student,ta,designer,observer
