SCP Keycards

- Properly aligned hitbox on the keycard readers (still need to place it in up and in front of the door for it to work, due to some limitations. But now it can be activated exactly where it looks to be.);

- New keycard designs;

- Curios implemented, now keycards can be equipped on the necklace slot, but for now it doesn't have a visual model when equipped, and it won't let you activate a keycard reader;

- Fixed an audio bug where the "access denied" sound would play with any keycard together with the "access granted" audio, but this was done removing the audio. It will be reimplemented when I work around a fix for this issue;

- Added crafting recipes for keycards and readers!
