[WIP] Support bootstrap 4

[kvdveer]

Bootstrap 4 does not provide any new features for the pager or the paginator. Hoewever, its structure has changed a bit.

We can get away with just using a different template for bootstrap 4. This way we can also easily bring back bootstrap 2 support.

Any chance we could get this merged in? It's still easily rebasable against master (tried on my local fork). And seems to be working in our bs4 environment.

Bootstrap 4 beta is out! I just updated this PR to use the (hopefully final) formatting. It's available here. Please note BS4 has removed the pager component. I don't use it so I didn't do anything about it...

Any progress with this? :)

I'm getting the following error:

@kvdveer Is this still something you're working on? I've added basic support for Bootstrap 4 for the next release by simply adding the two additional required classes to the pagination tag. The pager tag is the tough one, alas. It doesn't seem to be supported at all in Bootstrap 4. I am wondering if we should just remove it. I looked at what you were doing here and wasn't sure if you were trying to make Pager still work?
