Fix gates with serverstep code.
Let's give that a try.

Action Queue bugfixes by Novatux

Resume turnon/off calls as soon as area is loaded in case turnon/off calls end in unloaded territory

This makes effectors nearer to the source of the action (the receptor) update first.

This defines behaviour for this piston circuit: http://i.imgur.com/9Pp2Mzb.png
And defines, that this memory circuit does not work from this direction: http://i.imgur.com/jJn0aFh.png
But it will work when using the switch from the other side: http://i.imgur.com/nvw0oZB.png

Only if two effectors have the same distance, there is nothing we can do about it, behaviour is not defined.
"Distance" is determined by the stack size of recursions in turnon / turnoff.
Priorities are between 0 (lowest) and 1 (highest).

First draft of some kind of Action Queue (just like the globalstep queue in to_update), but more flexible and also including delay functionality (mesecon_delayer).
The queue is also saved to a file, so that when restarting mesecons, delayers resume to the state they had when the game shut down. Needs testing.

Use swap_node instead of add_node when replacing conductors.

change on_punch to on_rightclick, make disabled blinky plants drop norma...

here and there to facilitate this.

Make blinkyplants toggleable
