[STUMP] Placement rules, automatic group create/restore

[Morgan Veyret]

Hello,

The following serie of patches add automatic group create/restore
functionnalities to window placement routines.

It add one parameter:
*group-dump-dir* which should point to a directory containing dumped
frames to restore if needed.

And three parameters to rule definition:
:dump-name: key parameter defining the dump file to restore instead of a
one with the group name.
create: when set, a new group is created as needed and if a dump file
named as the group exists it is used to restore the group layout.
restore: force layout to be restored even if the group exists (this may
be used along with :dump-name option)

See sample rc file for an example.
