[REL] v1.2.0

Owl v1.2.0

Changes

• translation fix for terms surrounded by spaces
• fix: properly remount components with shouldUpdate=false
• add: add two new generic hooks: useEnv and useComponent
• fix: do not skip rendering in components using store and local state (in some cases)

Note that the last change is a pretty significant change: component connected to
a store should be very careful if the data that they represent is deleted, because
they will always be rendered with the current state of the store.
