Add explicit slash for repetitions

[otonielpv]

When importing songs from Planning Center, lines with repeat markers (e.g., //Esto se repite//) had the // stripped from slide content — slides were correctly duplicated but the markers were invisible to the congregation.

Before / After

// Planning Center input:
//Esto se repite//

// Before:
SLIDE 1: Esto se repite
SLIDE 2: Esto se repite

// After:
SLIDE 1: //Esto se repite//
SLIDE 2: //Esto se repite//

This will help the congregation to know how many repetitions are

Is this really the intended behavior? Cause in my opinion, I would want to strip the slashes and just have the slide repetitions. With a proper transition, the audience should be able to know to continue repeating the line...

I've tested it for a couple weeks, and there are people that doesnt do the transition on time, so the congregation told me that it is a bit confusing

Hm... interesting... I found that doing a fade through black that FreeShow defaults to helps queue people to know that a slide changed and that therefore they should repeat it.

I guess this is a specific use case, that I wouldn't use much.

I would do this, like @thebiblelover7:
SLIDE 1: Esto se repite
SLIDE 2: Esto se repite
That's the reason why the default fade shows the text changing even when it has the same content, so people knows it repeats.

Either have the // unchanged from Planning Center, or have it on two slides without //, not both!
