Updated SDK Demo app with cleaner interface, added beep option (to show ability to customize sled settings)

Anthony: finally got scanner working.  Was missing three lines in Build Info.  Hopefully won't have to play this game again moving forward.

Updating view controller again based on testing; no light is showing, so I'm going to try forcing the decoder illumination and aimer

updated CaptuvoSDKDemo based on testing (handles pressing keys), also added CaptuvoSDK to repository

Updated with additional calls to hopefully get hardware working.  Removed some of the metadata (if this breaks the project on the repository side, I'll add it back in).
