factotum: rename mount and path configuration entries

The factotum extension used mount and path entries which were too
generic. These have been replaced by mountpoint and executable
(respectively) to match existing conventions.

 '''http authentication with factotum
 
 This extension allows the factotum facility on Plan 9 from Bell Labs platforms
 to provide authentication information for HTTP access. Configuration entries
 specified in the auth section as well as authentication information provided
 in the repository URL are fully supported. If no prefix is specified, a value
 of ``*`` will be assumed.
 
 By default, keys are specified as::
 
   proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
 
 If the factotum extension is unable to read the required key, one will be
 requested interactively.
 
 A configuration section is available to customize runtime behavior. By
 default, these entries are::
 
   [factotum]
-  mount = /mnt/factotum
-  path = /bin/auth/factotum
+  executable = /bin/auth/factotum
+  mountpoint = /mnt/factotum
   service = hg
 
-The mount entry defines the mount point for the factotum file service. The
-path entry defines the full path to the factotum binary. Lastly, the service
-entry controls the service name used when reading keys.
+The executable entry defines the full path to the factotum binary. The
+mountpoint entry defines the path to the factotum file service. Lastly, the
+service entry controls the service name used when reading keys.
