Some tweaks and bugfixes for the trash compactor...

Fixed little bug in trash compactor where it would not find a bag (it was only looking for stacks).

Added sound for trash compactor.

Changed the Trash Compactor by adding status lights to it. Also added more slots to this processor, so it can be used by up to 5 people simultaniously when storing garbage. It will shift sorted garbage which gets loaded at slots 3-7 to slot 0 and when the stack reaches 60 it will spit out a stack for the exports.

Some small changes in recycledesk to stop ghost garbage from piling up when no worker is present.

some other minor fix

minor fix in production rules

This is Recycling 2.0, where efficiency counts! A number of things have been done to make the recycling process better. Trash Bins have been introduced: put them around in your prison or in the Recycling room to collect and stack Unsorted Garbage. They come in various sizes to stack 10, 20 or 30 bags into one big bag of trash. Deploy them depending on your prison size and the amount of garbage it produces. To minimize garbage exports, you can invest in an optional Trash Compactor. Less garbage bags = more space on the truck for other things! When you buy the expensive Trash Compactor, the tiny bit of sorted garbage going to exports will bring some cash as well, so it will pay for itself.
