Add new design logos for Clever and Google

[mfonism]

This PR adds the new design logos for Clever and Google to NRI UI.

Two of them are currently named cleverFull and googleClassroomFull because the names I think they should actually take (clever and googleClassroom, respectively) are already used.

I made the decision to call add the -Full suffix for now so we don't have to track down where the older logos are used in NoRedInk/monolith to update them. The idea is that we can coordinate efforts to rename the logos to be consistent, and update their use in NoRedInk/monolith at a later time.

What do you think about this? Is there another way we could do this?

I'll be OOO until Tuesday, but feel free to move this PR forward/merge without any additional input from me. 😄
Mandla is also adding some icons -- you may want to coordinate the next release with him.
