Warn about using deprecated features

[gkubisa]

I've also removed doc from README.md because the other deprecated action, "after submit" was not there either.

Thanks, @gkubisa! Great idea to notify users about feature deprecation. I think we should start following this example with other breaking changes in ShareDB. 👍

I'm following this thread but I'm still not exactly sure how to get rid of these warnings. As far as I can tell these warnings are originating from the actual source code itself, and not the way I'm implementing ShareDB? Could someone please enlighten me? Thanks!!

@stanographer as the warning says, pass the disableSpaceDelimitedActions: true when constructing ShareDB to disable both the warning, and the middleware that uses spaced names.

@stanographer It was not obvious to me either, exatly where/how these options should be pased in.

It turns out they need to be passed as properties of the object passed as the first argument to the ShareDB constructor, like this:

constbackend=newShareDB({// The following options serve only to squelch errors.// It should be possible to remove these when ShareDB 1.0 is released.disableDocAction: true,disableSpaceDelimitedActions: true});constconnection=backend.connect();
