Dupport for waveform plotting

See merge request !20

Also fixed small channel 3 issue

The selection mode was being returned with an inverted value.

Also avoid problem with processing extra 15th byte of the title for situations where the CGB flag is present.

Improves performance of APU by an order of maginute at the cost of less accurate emulation.

There's still no control over the channels themselves, but the basic interleaved buffer support is now coded.
There's also new support for buffer size definition in seconds.

Will allow performance update when not using audio.
Done for benchmark purposes.

Support for set of video, audio and timer.
Now with support for toggling audio in the SDL version.

This is specially useful for disabling APU if not used.

Using a dequeue it's possible to control the size of the queue and outdate old elements.
