Clean .vimrc.bundles

fix bug of .vim directory

In the repo, there's no .vim directory, so I think the shell should
create it first.

Move test for whitespace stripping out of function.

Rather than have the function call be a noop, which is misleading and a waste of
resources, this commit simply moves the conditional test up to the call site. If
g:spf13_keep_trailing_whitespace exists then we simply don't call the Strip()
function. This way Strip() can just do its job when called. I, for example, have
<leader>ws bound to this function and call it manually when needed. Hiding the
conditional inside the function broke that.

Conditionally override airline separators only if powerline fonts are not used.

The Airline separators were unconditionally overridden. I have conditionally overridden the separators only if the user doesn't use Powerline fonts.

User is expected to specify `g:airline_powerline_fonts=1` in `~/.vimrc.before.local` instead of `~/.vimrc.local`.
