Register autocmds once

This commit changes the autocmd registration in vimwiki so that
registration happens once rather than once per extension.

Instead of the following,

    autocmd BufEnter *.md call s:setup_buffer_enter()
    autocmd BufEnter *.mdown call s:setup_buffer_enter()

We'll now only run,

    autocmd BufEnter *.md,*.mdown call s:setup_buffer_enter()

This probably has no effect on performance but it makes for a simpler
implementation.
