CLOUD: Add Storage saving mechanism

In this commit CloudManager starts supporting multiple Storage. Now, in
its init() it loads all the Storages and determines the current one.

It now also has save() method. In that method all Storages are saved
with their new saveConfig() method.

CloudManager::save() not called from anywhere, though. The only one
Storage that could be added is DropboxStorage in case you have no
cloud-related config keys or you have no storages connected.
