Consistent import naming for redux associated imports

[MaybeJustJames]

Just a general comment. I noticed that the import of this module (and others) is not named consistently.
I have seen actionTypes been imported as Action, t, AT... which makes it somewhat confusing.
Not a major issue, but having a consistent naming of modules could improve readability (especially if you are not very familiar with the codebase 😄 )
