Make all config file variables be settable in the environment

Browse Source 
These are set in the form RCLONE_CONFIG_remote_option where remote is
the uppercased remote name and option is the uppercased config file
option name.  Note that RCLONE_CONFIG_remote_TYPE must be set if
defining a new remote.

Fixes #616
