* removed existing test items, newtitle now returns arcade_level.new()
* rearranged stuff so initializers wouldn't complain
* specialized linked list to event list
* convert "strip" to "update" -- strips based on update calls
* removed assorted list manipulations I don't need
* stupid sky/sea prototype
* assemble overall frame
* assorted placeholders and todos
* since sky will probably be blue, plan for a pink dolphin
* splash callbacks now part of the level, dolphin is told what to
call back into; may rework this latre when I am trying to squeeze into
token limits
* added time offset arg to wave generator, although I am not sure I will
actually use it
* noted plan to change wave pattern to look more sea-wave-y. wave curl
is probably not going to happen, though, since that can't be expressed
as a pure Cartesian function due to multiple Y values for an X
there's something wrong with mknew's attempt to do inheritance. I need to figure out why it's wrong, but for now I think the animator and linked list are just noise.
