Identification card placeholder art (#727)

* Imported Eiko's prototype ID art as a placeholder.
Realigned textboxes on ID card prefab.
Made gender field invisible as it had no place on the prototype.

* Networked the ID examine interface so each card displays the same details on server and client.

* Changed ID font to Do Hyeon.

* Added changeable ID mugshots, so that each ID shows a different person.

* Deleted the now-redundant IDExaminable class.

ID's are now examined through the IdentificationCard.cs class.

* Renaming files to comply with naming conventions, and removal of unneeded debug calls / comments.

* Changed Contents/Systems/Examine/UI folder to Content/Systems/UI/Game/Examine.

* Resolved issue where visual examine UI's weren't being displayed until the mouse hovered over another object.

* Amended CompositeItemSelector to ensure null meshes weren't able to be added. This resolves the issue where items on Janicart are unable to be examined. This closes the primary issue in #464.

* File renames

* File rerenames
