New allout revisions

[Ken Manheimer]

attached is a ChangeLog and patch for some refinements of allout.el. 
the most signficant changes are marking some commonly used allout file
local variables as safe, according to the new system, and
establishment of a custom variable for the default allout layout spec.
 see the ChangeLog for more details.

(in crafting the allout-default-layout custom variable type i was
blocked by what seems to be a limit in the customization type
protocol.  the layout spec allows for nested expressions that are
themselves layout specs, and so the type form is self-recurrent.  i
see no way, however to declare self-recurrent or even
indirectly-recurrent type definitions.  is there a way, in the current
custom types system?)
