make drawer component drop in the right side instead of the left side if the document dir is rtl

[IMythx]

hey thx for the great work

i wonder if we can change the drawer drop side to the right side (instead of the default left side) if the document dir is rtl automatically or via a prop to the drawer component

Not currently possible unfortunately but likely to change soon as I resolve #123, which is changing the underlying dnd implementation.
