Add toggle command for Bible Icon Prefix setting, and add collapsible option for callout options

Notice the extra space that the extra <br/> tag makes when it is included?

Being able to switch between callouts and blockquote is a must have feature for me.

I'm also thinking about working on a toggle in the settings for if you want only the body text of the verse, no headers, or anything, just plain scripture. It would make it a lot easier to quote stuff on the fly.

Hi @AlphaHasher

Thanks for your contribution, if you don't mind, can you explain the differences?

From the screenshot, I cannot see the differences between with or without <br/> .

[AlphaHasher]

Absolutely, there is extra space under the verse when br is included.

[tim-hub]

I am not sure which is better.

Add None here or keep existing behaviour.

Does existing setting do the same things? Of Reference Position.

[AlphaHasher]

I say keep it None. Also, the setting you point out does not affect the new option I added.

To make it clearer, I started testing (on my dev branch) disabling settings depending on other settings (e.g., if you don't want to use callouts, then the collapsible option can be disabled) but I ran into odd performance issues which I documented there.

[tim-hub]

Could you take a screenshot when the setting is CollapsibleVerses.None, at the same time, reference position is Header?

I am not sure what are the differences.

Thanks

[tim-hub]

Absolutely, there is extra space under the verse when br is included.

Thanks I see now

May I make a humble suggestion?

• To split the
  changes and collapsing changes to 2 different PRs.
• 
  changes are very clear and straight-forward.
• The collapsing changes I am not very sure.

[AlphaHasher]

Yes, I'll split them up

[AlphaHasher]

I have an idea. Since this pr relates to callouts, there can be a single settings whether the user wants to use callouts or not. If yes, it will shows more options, like whether or not they want it to be collapsible or not. Right now it is complicated and the end user would not know what settings do what.
