Title: Global and local env configuration

The applications I deploy with dokku are almost identical with their ENV setup. Changing common things, like DB connection strings thought all application is a bit painful thing.

This PR introduce global and local ENV configuration.

`/home/dokku/ENV` - global one, shared among all applications.
`home/dokku/$APP/ENV` - local one, contains app specific ENV variables + able to override global ones.
