Could you also replace the build status badges in README.md with this one?

Can you also add:
Streamer_HasFloatData and Streamer_RemoveFloatData.

Also there's an issue with E_STREAMER_CUSTOM as it accepts integer data related only instead of them all. (Streamer_GetIntData, Streamer_SetIntData). It just would print Invalid data specified.
