This commit refactors the Store interface in State into smaller interfaces in package store. These interfaces are combined into one structure called a "Cabinet". The default implementation of those interfaces have been rewritten in package defaultstore, while the old no-op implementation stays with the store package. This commit also omitted several state handlers for user events, as it is unclear what they are actually structured like.
