Add <Plug>(vaffle-chdir-current)

[ichizok]

I want a simple way to change the current directory to the path vaffle buffer shows :)

Thank you for the pull request!

I think the feature is nice, but need to consider its name. Maybe -chdir means 'change directory', but the actual feature is 'changing working directory to the current directory'.

I'm concerned some users expect vaffle#chdir('somedir') shows contents in the specified directory.

What do you think about this?

Hmm, vaffle-cd-to-current? (ugly?)

And I changed vaffle#chdir() accepts path optional argument.

I changed to <Plug>(vaffle-chdir-current).

I still wonder what name is appropriate.. changed to <Plug>(vaffle-chdir-to-here).
