From 0.x to 1.0

Most of the config file is remained compatible, however to clean up the backends custom environment variables were moved from the root object to an env object.

# Before
remote:
    type: b2
    path: bucket:path/to/backup
    key: some random encryption key
    B2_ACCOUNT_ID: id
    B2_ACCOUNT_KEY: key
 
# After
remote:
    type: b2
    path: bucket:path/to/backup
    key: some random encryption key
    env:
      B2_ACCOUNT_ID: id
      B2_ACCOUNT_KEY: key

Other than the config file there is a new -v, --verbose flag which shows the output of native commands, which are now hidden by default.
