launch types

[danielghost]

Look to include the following launch types:

• ADL xAPI - https://github.com/adlnet/xapi-launch, https://github.com/adlnet/xAPIWrapper#xapi-launch-support
• cmi5 launch - https://github.com/AICC/CMI-5_Spec_Current/blob/quartz/cmi5_spec.md#content_launch
• Rustici launch - https://github.com/RusticiSoftware/launch/blob/master/lms_lrs.md#launch
  Hardcoded?

Considerations:

• Is there an algorithim where the launch type could be determined automatically?
• Multiple launch types to different endpoints
• SCORM + xAPI

contextActivities don't seem to be consistently sent through in each launch type. Requires investigation.
