Updated rake gem from 10.1.1 to 10.2.0
Fixed several errors introduced in 264d9a2f84437ae7788ce1dfb68b751782bfb12e:

- the namespace for API controllers cannot be "API::". It has to be "Api::". I've found no way around rails default capitalization rules for this.

- in feeds and folders show views, a reference to the entries show view has been updated so that the view is found in its new location under the "api" folder.
