More consistent submodule names

Most submodules are action-block; views were block-view.
Swapped those to be in line with the rest of the names.

There may be some cache issues (cached JS still firing old
block-view formatted API calls which will not be understood
by new API) but I think we can safely ignore those since
this branch, with the new JS making the calls, is not
deployed yet, so noone should have that in browser cache yet.
