Support Bootstrap 4 popover

[KuroNoDev]

Bootstrap 4 uses popover popover-{placement} instead of popover {placement}
and popover-arrow instead of just arrow not making the popover arrow appear.

I will look into it, but Bootstrap 4 is still in alpha so it will be lower priority for now.

Hey @KuroNoDev, just to update you on this: I looked into it, I was able to get most of the styles working fairly easily, but Bootstrap 4 switched to ::before pseudo-elements for arrows, so I'm going to take some time to implement this correctly. I'll probably include a config option to choose Bootstrap 3 or 4, and basically just swap out the template and include the correct styles. That will happen once Bootstrap 4 releases a stable version.

Hey guys, have you found a workaround or it's impossible to work with bootstrap 4 at the momment?

Any update on this? I'm actually having issues making Angular UI working with Bootstrap 4. The tour work but I can't seem to be able to inject a custom template to fit the Bootstrap 4 format.
