Improved Show manager show event. Much faster now

Temporarily disabled workaround for sequences switchFunction. TODO!
Fixed fast stop/start of a function with the same ID (including fade setting)

Reduced CPU usage of audio renderer thread
Use specified duration in Efx preview
Remove parameter 'direction' - replace it with efx's own direction().
Add unit tests for backward direction.

The backward path is not an exact copy of the forward path due to rounding,
but it's good enough for now.
Take effect's direction in account.

Now both EFX::direction() and EFXFixture::direction() are considered.
EFXFixture::direction() is relative its EFX's direction().

That means if both are Backward, it is the same as if they both were
Forward.

Until now, only EFXFixture::direction() was used for the movements.
