Ghost Shell Perks

Perks
Ghost Shell Perks are attributes that are obtained when the player equips a certain Ghost Shell onto their Ghost.

There are 3 different types of perks:
 * Ghost Module - Ghost Modules grant the player passive abilities, such as an experience boost, locating chests nearby, or boost token acquisition.
 * Ghost Stat Tracker - Ghost Stat Trackers will record different stats, like kills in the Crucible, or Raid encounters defeated.
 * Intrinsic - Intrinsic perks are specific to one or a few Ghost Shells, and thus are a little better than regular perks.
