Sort by buffer number

[sricks]

I've never used vimscript but I could try to add this.

I would like the buffers to be sorted by buffer number. Could even be an optional flag.

Problem:

• You close and re-open the same file in the same session
• Therefore the buffer numbers and position don't match up
• Using :bnext therefore does not go to the next buffer in the visible list

I use bnext to navigate between buffers, and it gets confusing if they're out of order. Would you take a PR for this if I could figure it out?

Nevermind, this was bugged on an install of mine but I reinstalled and seems to work properly. Looked through the source and saw that option
