Update:
- Just a few performance and reliability optimizations.

Update:
- Attempt at fixing the buttons not getting placed.

Update:
- Made the collisions for some walls even thinner. Hopefully that will help with some blocks like the Vent Filler blocking the elevator.
- Changed the airtightness for some of the blocks. Please let me know how is it behaving now.

Major Update:
- Elevator is now based on a piston block. That means:
There is only one Elevator block with a slider to select elevator speed.
It works much more reliably in multiplayer.
You can change your target floors even when moving.
Stops perfectly even with the floor every time.

All existing elevators will be replaced automatically, except in the cases where that may cause a split in the grid. In those cases the old elevator block will be renamed and it will turn on Show on HUD so you can see which one didn't replace and do it yourself.
Automatically replacing the blocks means that you will loose any previous settings for music and light in the cabin (Sorry about that). You will also need to set up the desired speeds for each elevator. By default it starts at 2m/s.

Other new features and improvements:
- Added Double Middle Floor. It's purpose is to provide level stopping with half blocks.
- Added a "Ding" sound when the elevator stops (can be turned off in control panel).
- Added automatic Voxel clearing from around all elevator blocks. Pistons are too sensitive to this stuff and can get caught on the smallest piece. This way I can "guarantee" more reliable operation without having to always ask "Is it cleared enough from voxels?".
- Added a Stop button inside the cabin. (I realize it's not very useful in a closed cabin. It was originally intended to be used to change the floor after the elevator starts but now I do that without stopping first. And I am too tired now to remove it... Maybe at some later point.)
- Some performance improvements.
- Probably some other small things here and there but the code has changed so much and I don't remember what was in before and what wasn't.

Update:
- Temporary fix for Keen's bug with door subparts when it gets characters stuck on the edge when exiting the elevator on Middle and Top floors. (Slightly higher collision for the cabin floor. There could be a slight "bump" when entering the elevator but it works for now.)

Update:
- Fixed teleporting back to starting position when reaching target floor.

Update:
- Added Music Volume Slider;
- Added Cabin Light with controls for Color, Range and Intensity

Update:
- Fixed not being able to hear the music in non-pressurized environments on Realistic Sound mode.

Update:
- Taking down the Christmas lights. ;)
- Added 3 additional music tracks.
- Added slider to select which track you want to be played.
- Added an option to start playing music when you get close to the elevator even if it has not started moving.
- Improved detection of block changes. Should resolve some caseses where you change blocks of the elevator but it doesn't correctly update it's status.

A Christmas special update! :)
+ Changed the 15m/s elevator to actualy be 15m/s (I had left it at 20 by mistake)
