Add a move(source:list[DriveNode], dest:DriveNode) method to ICloudDriveService

Tim,

Currently there is no way to move files from A to B. To achieve with the current implementation I have to delete and upload.

Is this something you'd have the time to do ?

I took a quick look in the JavaScript console in Chrome and it looks like a straightforward post to /moveItems with a payload that includes the destinationdrivewsid and an array of items.

Let me know if you can. Otherwise I'll fork, implement and make a PR.
