Ciaran Gultnieks 9eda62df7b Add timer() function/event (node timer based) to luacontroller
This adds a timer(<seconds>) function, which causes an event of type
"timer" to be fired after that many seconds has elapsed.

Because it's node timer based, it works properly across server restarts
and block unloading. Thus, simplest example, a blinky plant replacement
with a 10 second period:

if event.type == "program" then
  timer(10)
elseif event.type == "timer" then
  port.a = not port.a
  timer(10)
end

Ciaran Gultnieks 5d3cba0bd4 Handle luacontroller formspec events correctly
Example of problem fixed by this: Edit lua code, press Execute. Now
(execute button has focus), hold down a key. Zillions of "program"
events are generated.

Ciaran Gultnieks 5002315ec9 Send digiline messages after luacontroller execution
In the same way as for port settings, this queues up digiline messages
sent during the luacontroller's execution, and sends them afterwards.
This solves many problems, but one example:

1. Send a message, and receive a reply from another device.
2. While handling the reply event (effectively a nested invocation
   on the same luacontroller) make a change to memory
3. Notice that the memory change has no effect, because after
   completion of the reply handling, it stores the memory, but then
   the original invocation completes and overwrites it with it's
   own earlier copy of the same memory.
