add start music after voice lines checkbox

add a start music after voice lines checkbox so the voice line chosen will play first and then the test chamber music starts when the voice line ends.

This doesn't seem very useful. Can you give an example of where you would use it?

It's useful to make it easier to hear voice lines.

[vrad-exe]

Maybe with some tracks, but with most you can hear it just fine.

Yeah I still don't really see a use for this, most music isn't loud enough to drown out voice lines and the volume of other sounds lowers when a voice line plays anyway.
