Added wave_color attribute to the clip object, which now allows the audio wave form to animate it's color along a curve over time. Combined with the timeline background color curve, some cool combinations can be made!

Added curve-based color as the canvas background color (red, green, and blue), so it can be animated now.

Refactored the audio waveform generation into the Timeline class. Added the ability to set the volume, and the ability to mix layers of audio samples together. Also, made the waveform's have a transparent background, so they can be layered on top of other layers.

Fixed more audio issues, and a regression where removing the video channel (with just an audio channel remaining) caused the FPS to be incorrect.

Fixed a big audio bug, where varying timestamp values on low precision audio timebases (i.e. 1/1000) would leave small gaps in the audio wave. Also, fixed a few issues related to sample_rate getting lost between the reader and clip and timeline objects.

Added in more conditional checks for older versions of FFmpeg, so libopenshot will compile on more platforms.

Updated the FFmpegWriter to use compiler #IF commands to be compatible with older and newer versions of FFmpeg. This is still a work in progress, but many of the newer commands are now being protected.

Replaced the opacity() method with the IM quantumOperator method, which allows me to simply multiply the alpha percentage to each alpha value, and fixed a bug in the ImageReader which prevented copying pixel data between frames.

The timeline classes are finally working correctly, and have the following features:
1) Layers (unlimited # of layers)
2) IN, OUT, and Position (time)
3) X, Y offset
4) Alpha
5) Rotation
6) Transparency + compositing + overlays

Replaced avcodec_encode_audio with avcodec_encode_audio2, and completely redid the way PTS values are calculated and set. Another nice improvement!
