DNA scanner pods now open and close like crates. This has fixed the following:
*Resolves #252 - Contents of dna scanners will be ex_acted properly.
*Resolves #125 - Mobs chestbursting in the scanner pod will no longer cause issues with entering/exiting the pod. The larva will be able to slither out (assuming it isn't locked), upon which the icon_state will update. Or it may be opened externally in a similar fashion.
*Items are no longer lost inside scanner pods when a mob is inside the pod with items and it mutates into a monkey or something.
*There are no longer any restrictions on having inorganic items on mobs being scanned.

Special thanks to Cheridan for the sprite-changes.

Adds a new assembly, the voice analyzer!
It can record an activation message, and when it hears that message thereafter, it will send a pulse.
Changelog entry.
Map updated as per Tenebrosity's request - tables moved in genetics.

Resolves #140 - doors/shutters now toggle based on the current state of the first door/shutter located in the loop.
This means you shouldn't have to press the button multiple times to open medbay doors (unless only one door is open and the other closed)
These changes also mean that blast-shutters no longer get out of sync with eachother. For instance, in rare cases one of the security lockdown shutters would be in the opposite open/close state to the others, rendering them totally useless.
Fixes maps to work with door_control changes

Removed /obj/effect/begin and /obj/effect/laser. Both were unused.
Updated chem grenades. They use assembly holders instead of snowflake code for each assembly.
The build process is much the same, except they require an igniter-X assembly instead of a single assembly item. You can also just use a cable coil to get regular grenade behaviour.

Updated the changelog.
Removed var/special_assembly from assembly_holder as it was unused.
Updated singletank bombs to pass hear_talk to their assembly.
