Updated; include status bar and improved window management.

Add eglglessink to default configurable sinks.

Improve window size management and automatically use aspect ratio
adjustment provided by xvimagesink. Also take advantage of the
automatic expose handling by most video sinks.

Listen for dropped frames (info not used yet).

Automatically detect xvimagesink and correct a mismatch in reported
channel names in GStreamer 1.0.x and xvimagesink when using color
balance control.

Implement status bar with seek slider. Seeking is currently smoother
when using GStreamer 0.10 than when using 1.0 for unknown reasons.

Fix the optimized video decode pipeline options that are not using playbin.
