Consider using bbye for closing buffers

I think it will be more intuitive for people.

For instance when you close a buffer but three are open and then the editor just closes.

Oh yes I use something similar in my config. Though I never use the close buttons, I just find them aesthetically pleasing. I wonder if it should be included as a dependency or if we should just distribute it directly with barbar.

I want to add that when closing buffers using bbye's :Bdelete the buffer tab of the deleted buffer isn't properly removed like for :bdelete. Perhaps a new issue should be created for this.

I've made a draft fix for :Bdelete issue in #20, though I by using timers it's introducing latency that I can clearly perceive, so I don't think I will be merging that :/ I don't have that issue because my custom function to close buffers triggers a BufEnter autocommand after closing the previous buffer, which isn't the case for bbye.vim. This should probably opened as an issue in bbye, because there are no after-buffer-close autocmd. There are after-win-leave, but because of bbye the win-leave happens before the buf-close.

I would however be open to distributing a fixed version of bbye.vim including the trick above. I've been thinking about implementing BufferClose and BufferOpen commands in barbar, among other things to be able to open a buffer after the current one, not at the end of the list.

Done. I've include bbye. Let me know if there is any issue with that update.
