More user-friendly LualineBuffersJump (#780)
* buffers: user friendly LualineBuffersJump version LualineBuffersJump throws an error when an attempt to jump to a non-existent buffer index is made. It's expected from users to trigger this error by accident while attempting to switch buffers. To deal with this add <bang> support to LualineBuffersJump.
