Add shortened class name component

[collinsmith]

Player entities are all of class type player, however some columns in excels (skills.txt "charclass" and overlay.txt "Character") refer to a specific class, or class of types (objects, all, items, monster). I need to look into the possibility of adding a shortened class name component, or appending it to the already existing classname component.

The workaround for skills.txt is simple, since it only refers to character classes, however overlay.txt is more complex (unsure how that column is used, if it even is). I don't want to jump onto this until it has been looked into more, since it may require something more complex than I initially intend.
