The "global" action constants (the ones previously in `actions.js`)
have been moved to a separate module. This was necessary to avoid a
circular dependency in an upcoming change that was causing problems.
In general the "ducks" pattern of organizing Redux stores does result
in circular dependency problems. This is because reuse of actions
between reducers is encouraged, so it's not uncommon for two reducers
to want to reference an action from the other. Going forward we can
avoid this problem by moving action constants that are shared between
reducers into this shared module.
* Remove unused functions from `mapDispatchToProps`
The actions import was also updated to import only the two actions
used, rather than all actions.
* Remove unused container component
Well, technically it was the props injected by this container that were
unused. The container served no purpose, so the component it surrounded
is now used directly instead.
* Remove both unused `getCurrentViewContext` selectors
* Remove unused SHOW_CONFIG_PAGE action
* Remove checks for `currentView` with name `config`
Now that the SHOW_CONFIG_PAGE action has been removed, it's no longer
possible for `currentView.name` to be set to that value.
* Remove unused `wallet-view` container props
* Delete unused SHOW_SEND_PAGE and SHOW_ADD_TOKEN_PAGE actions
* Remove unused `account-menu.container` props
* Remove unused SHOW_INFO_PAGE action
* Remove unused SET_NEW_ACCOUNT_FORM action
