Xenos gamemode rework

Changes:
1) The X-ray gun projectiles now stop after 50 tiles.
2) The telescience console now starts with 0 crystals (crystals are now on the table next to the console).
3) Cargo telepads can now be unanchored again.
4) Inflatable wall boxes now have a sprite.
5) The blob gamemode now has a separate antagonist preference.
6) Syndicate encryption keys bought through the uplink now give the right key, and that key now includes the Syndicate channel.
7) Reworks the Xenos gamemode.

First of all, apologies for the lack of mapmerge. I figured no-one else was editing the map, and after I made numerous minor changes to the map at some point I forgot to merge.

Secondly, I can not entirely guarantee that the Xenos are completely bugfree at the moment. As is always the case with such major changes, it's impossible to test them all thoroughly. Additionally, I can't guarantee perfect balance either. If it turns out Xenos are too powerful now, there's some things that can be nerfed.

- [X] Removes the Alien AI/Alien Cyborg. Can be re-enabled by switching a variable.
- [X] Updates the Xeno shuttle so it has unique airlocks which can only be opened by aliens. It also has shutters on its windows, simulated floors and a SMES to make sure the AI (if it's ever re-added) has power).
- [X] Facehuggers (and alien embryos) are no longer player controlled. Larvae that pop are.
- [X] The Alien Queen/Empress/Praetorian now have regular sprites. There's no unique sprites for the Praetorian/Empress though, so someone might have to design those at a later point.
- [X] The gamemode now ends properly when either the crew dies, the aliens die or the crew escapes. The end message now includes a list of all aliens and the people that played them. 
- [X] A variety of UI changes for all aliens.
- [X] Alien Hunters can now leap.
- [X] It now takes time to construct resin structures, as well as eggs.
- [X] Other buffs and nerfs I forgot about.

There's probably some things I missed, so it's mostly a matter of testing the changes now.
