Incorrect type vocab for SCORM 1.2 and SCORM 2004

[jonopoltrack]

In SCORM2004.cs and SCORM1.2.cs, the interactionTypeType enum is incorrect. The binding of the "multiple_choice" interaction type should be "choice", not "multiple_choice".

SCORM 2004 page RTE-4-48
Format: The format of the data model value shall be one of the
restricted tokens listed above (“true-false”, “choice”, “fill-in”,
“long-fill-in”, “matching”, “performance”, “sequencing”, “likert”,
“numeric” or “other”).

This example doesn't work with Unity 4x. Every time I make a SCORM package following this tutorial I am told I need to install the Unity web player.
