Restore standard widgets to fix segfault when re-sourcing autosuggestions.zsh

[ericfreese]

Adds $ZLE_AUTOSUGGEST_ALL_WIDGETS array which groups self-insert, magic-space, backward-delete-char, and accept-line with other widget arrays for easy looping.

Removes all references to autosuggest-*-orig widgets in favor of the '.'-prefixed names (i.e. .self-insert instead of autosuggest-self-insert-orig)

Extracts widget setup code to two new functions: autosuggest-hook-widgets and autosuggest-restore-widgets

Calls autosuggest-restore-widgets when sourced to fix issue #84.

Tested locally with zsh 5.0.7 and 5.2.

Have the installation / usage instructions changed as well?

What I mean to say is, I want to use this IMMEDIATELY, what do I need to know?

They shouldn't have changed. It should just work as it did before, but with less segfaults.

But you know, I'm playing with it now, and it definitely seems broken... Maybe not ready to merge just yet.

After working on ericfreese/zsh-autosuggestions though, I'm personally inclined to just go that route instead of messing with fixing this.

If you're saying it is more broken than it was before - I don't believe you.
