Added a videoconverter and filter caps to the AppSrc bin so that if the image is color, it's converted to I420 (if it's mono it stays GRAY8).

Changed order of encoders back to omxh264enc first, because v4l2h264enc had some problems on raspberry pi, and we only really use that encoder for the Snapdragon 820 devices which are less common.

Adjusted the method of applying rescaler caps, so that always we put caps on it, even if we are not rescaling. This is so we can have a clear caps for the final bin, which includes format, width, height, and framerate.

MAJOR CHANGE: New folder structure, renaming of pylongstreamer sample to demopylongstreamer, addition of new sample programs, and cleanup of readme and documentation. The reason is to clarify the relationship of the sample programs to the core of the project, the InstantCameraAppSrc class. Also, this structure offers flexibility for adding more sample programs to help with the diversity of systems which may use this project.

new feature: use your own gst-launch-1.0 pipeline. Use -parse and paste the command, and the PipelineHelper will parse it and replace your original source with the InstantCameraAppSrc. Also added some more notes to the user about using pylongstreamer with Nvidia TX1/TX2.

fixed issue #3 and issue #4. Issue #3 fixed by adding an additional caps filter to the CPipelineHelper::build_pipeline_display(). On Nvidia TX1 and TX2, the videosink found by autovideosink seems to not advertise the formats it supports, so we must tell the converter element manually to convert the RGB image to I420 (or something else). Issue #4 fixed by moving gst buffer wrapping from CInstantCameraAppSrc::InitCamera() to CInstantCameraAppSrc::retrieve_image()

Bugfix (API Break): moved control of h264file file size from pipelinehelper to instantcameraappsrc. Pipeline helper was setting num-buffers on source, but source is a gstbin made by instantcamerappsrc, so it is not possible to access the child appsrc element like this. pylongstreamer:numFramesToRecord is now applied to appsrc element in instantcameraappsrc:GetSource() before element is binned. additionally, the binned source now forwards the appsrc's EOS message to the pipeline when num-buffers is hit. Finally, removed muxer from pipelinehelper:h264file pipeline. It caused negotiation error with omxh264 (odd, but at least this was seen on rpi3 today...). API Break: pipelinehelper:h264file no longer accepts number of frames to record as argument.

InstantCameraAppSrc: new features (api break): now provides a gst bin element as a source, which includes appsrc+rescaler+rotator (previously just appsrc was provided). GetGstAppSrc() now changed to GetSource() and m_source is now m_appsrc. Fix: moved device enumeration and attachment of camera to device from InitCamera() to constructor. This makes it possible to change settings of camera before calling InitCamera(), for example if you want to reset the camera to default settins first.

Streaming video to browser?
Would anyone like an additional pipeline built which would allow browser-based access to a camera's video stream?
If so, do you have a preference on which webserver should be used as part of this reference sample?
(Browser access requires sinking the pipeline to a webserver on the device with the camera. This could be Apache, Icecast, etc.)
Let me know your thoughts!
