git-annex/Config.hs
Joey Hess cfaae7e931
added an optional cost= configuration to all special remotes
Note that when this is specified and an older git-annex is used to
enableremote such a special remote, it will simply ignore the cost= field
and use whatever the default cost is.

In passing, fixed adb to support the remote.name.cost and
remote.name.cost-command configs.
