fixes #387 and https://github.com/robbyrussell/oh-my-zsh/pull/1321#issuecomment-9959540
and other problems of prompt overwriting when people did not realize that it
was vi mode causing the problem.  Hat tip to sorin ionescu, as I took this code
from prezto

the vi-mode plugin destroys any bindings made before it is sourced due to the
'bindkey -v' call to switch to using vi-mode.  This patch saves the bindings
before invoking 'bindkey -v' then rebinds them afterwards, this fixes a number
of outstanding issues due to people using vi-mode and having things in oh-my-zsh
break due to the bindings being destroyed

Reorganizing plugins so that each plugin has it's own directory now so that any plugin-specific functions can be bundled within there.
