[MAP] Syringe gun projectiles will now display a message when the shots are deflected by the THICKMATERIAL flag.

 * Fixes the space helmet not having the flag.
 * Fixes various coverall armour not having the THICKMATERIAL flag.
 * Fixes #2115 and the captain's space suit path was changed to /obj/item/clothing/suit/space/captain from /obj/item/clothing/suit/armor/captain
 * Updated the map with the new path.
 * Removed a debug message.
